lib/services/cloudsearchdomain.js

Overview

Note:

You must provide an endpoint configuration parameter when constructing this service. See constructor() for more information.

Constructs a service interface object. Each API operation is exposed as a function on service.

Sending a Request Using CloudSearchDomain

var csd = new AWS.CloudSearchDomain({endpoint: 'my.host.tld'});
csd.search(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the CloudSearchDomain object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var csd = new AWS.CloudSearchDomain({
  endpoint: 'my.host.tld',
  apiVersion: '2013-01-01'
});

You can also set the API version globally in AWS.config.apiVersions using the cloudsearchdomain service identifier:

AWS.config.apiVersions = {
  cloudsearchdomain: '2013-01-01',
  // other service API versions
};

var csd = new AWS.CloudSearchDomain({endpoint: 'my.host.tld'});

  • sslEnabled (Boolean)

    whether to enable SSL for requests.

  • paramValidation (Boolean|map)

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.
    • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
  • computeChecksums (Boolean)

    whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

  • convertResponseTypes (Boolean)

    whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

  • correctClockSkew (Boolean)

    whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.

  • s3ForcePathStyle (Boolean)

    whether to force path style URLs for S3 objects.

  • s3BucketEndpoint (Boolean)

    whether the provided endpoint addresses an individual bucket (false if it addresses the root API endpoint). Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor.

Property Details

endpointAWS.Endpoint (readwrite)

Returns an Endpoint object representing the endpoint URL for service requests.

Returns:

  • (AWS.Endpoint)

    an Endpoint object representing the endpoint URL for service requests.

Method Details

search(params = {}, callback) ⇒ AWS.Request

Retrieves a list of documents that match the specified search criteria. How you specify the search criteria depends on which query parser you use. Amazon CloudSearch supports four query parsers:

  • simple: search all text and text-array fields for the specified string. Search for phrases, individual terms, and prefixes.
  • structured: search specific fields, construct compound queries using Boolean operators, and use advanced features such as term boosting and proximity searching.
  • lucene: specify search criteria using the Apache Lucene query parser syntax.
  • dismax: specify search criteria using the simplified subset of the Apache Lucene query parser syntax defined by the DisMax query parser.

For more information, see Searching Your Data in the Amazon CloudSearch Developer Guide.

The endpoint for submitting Search requests is domain-specific. You submit search requests to a domain's search endpoint. To get the search endpoint for your domain, use the Amazon CloudSearch configuration service DescribeDomains action. A domain's endpoints are also displayed on the domain dashboard in the Amazon CloudSearch console.

Service Reference:

Examples:

Calling the search operation

var params = {
  query: 'STRING_VALUE', /* required */
  cursor: 'STRING_VALUE',
  expr: 'STRING_VALUE',
  facet: 'STRING_VALUE',
  filterQuery: 'STRING_VALUE',
  highlight: 'STRING_VALUE',
  partial: true || false,
  queryOptions: 'STRING_VALUE',
  queryParser: simple | structured | lucene | dismax,
  return: 'STRING_VALUE',
  size: 0,
  sort: 'STRING_VALUE',
  start: 0,
  stats: 'STRING_VALUE'
};
cloudsearchdomain.search(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • cursor — (String)

      Retrieves a cursor value you can use to page through large result sets. Use the size parameter to control the number of hits to include in each response. You can specify either the cursor or start parameter in a request; they are mutually exclusive. To get the first cursor, set the cursor value to initial. In subsequent requests, specify the cursor value returned in the hits section of the response.

      For more information, see Paginating Results in the Amazon CloudSearch Developer Guide.

    • expr — (String)

      Defines one or more numeric expressions that can be used to sort results or specify search or filter criteria. You can also specify expressions as return fields.

      You specify the expressions in JSON using the form {"EXPRESSIONNAME":"EXPRESSION"}. You can define and use multiple expressions in a search request. For example:

      {"expression1":"_score*rating", "expression2":"(1/rank)*year"}

      For information about the variables, operators, and functions you can use in expressions, see Writing Expressions in the Amazon CloudSearch Developer Guide.

    • facet — (String)

      Specifies one or more fields for which to get facet information, and options that control how the facet information is returned. Each specified field must be facet-enabled in the domain configuration. The fields and options are specified in JSON using the form {"FIELD":{"OPTION":VALUE,"OPTION:"STRING"},"FIELD":{"OPTION":VALUE,"OPTION":"STRING"}}.

      You can specify the following faceting options:

      • buckets specifies an array of the facet values or ranges to count. Ranges are specified using the same syntax that you use to search for a range of values. For more information, see Searching for a Range of Values in the Amazon CloudSearch Developer Guide. Buckets are returned in the order they are specified in the request. The sort and size options are not valid if you specify buckets.

      • size specifies the maximum number of facets to include in the results. By default, Amazon CloudSearch returns counts for the top 10. The size parameter is only valid when you specify the sort option; it cannot be used in conjunction with buckets.

      • sort specifies how you want to sort the facets in the results: bucket or count. Specify bucket to sort alphabetically or numerically by facet value (in ascending order). Specify count to sort by the facet counts computed for each facet value (in descending order). To retrieve facet counts for particular values or ranges of values, use the buckets option instead of sort.

      If no facet options are specified, facet counts are computed for all field values, the facets are sorted by facet count, and the top 10 facets are returned in the results.

      To count particular buckets of values, use the buckets option. For example, the following request uses the buckets option to calculate and return facet counts by decade.

      {"year":{"buckets":["[1970,1979]","[1980,1989]","[1990,1999]","[2000,2009]","[2010,}"]}}

      To sort facets by facet count, use the count option. For example, the following request sets the sort option to count to sort the facet values by facet count, with the facet values that have the most matching documents listed first. Setting the size option to 3 returns only the top three facet values.

      {"year":{"sort":"count","size":3}}

      To sort the facets by value, use the bucket option. For example, the following request sets the sort option to bucket to sort the facet values numerically by year, with earliest year listed first.

      {"year":{"sort":"bucket"}}

      For more information, see Getting and Using Facet Information in the Amazon CloudSearch Developer Guide.

    • filterQuery — (String)

      Specifies a structured query that filters the results of a search without affecting how the results are scored and sorted. You use filterQuery in conjunction with the query parameter to filter the documents that match the constraints specified in the query parameter. Specifying a filter controls only which matching documents are included in the results, it has no effect on how they are scored and sorted. The filterQuery parameter supports the full structured query syntax.

      For more information about using filters, see Filtering Matching Documents in the Amazon CloudSearch Developer Guide.

    • highlight — (String)

      Retrieves highlights for matches in the specified text or text-array fields. Each specified field must be highlight enabled in the domain configuration. The fields and options are specified in JSON using the form {"FIELD":{"OPTION":VALUE,"OPTION:"STRING"},"FIELD":{"OPTION":VALUE,"OPTION":"STRING"}}.

      You can specify the following highlight options:

      • format: specifies the format of the data in the text field: text or html. When data is returned as HTML, all non-alphanumeric characters are encoded. The default is html.
      • max_phrases: specifies the maximum number of occurrences of the search term(s) you want to highlight. By default, the first occurrence is highlighted.
      • pre_tag: specifies the string to prepend to an occurrence of a search term. The default for HTML highlights is &lt;em&gt;. The default for text highlights is *.
      • post_tag: specifies the string to append to an occurrence of a search term. The default for HTML highlights is &lt;/em&gt;. The default for text highlights is *.

      If no highlight options are specified for a field, the returned field text is treated as HTML and the first match is highlighted with emphasis tags: &lt;em>search-term&lt;/em&gt;.

      For example, the following request retrieves highlights for the actors and title fields.

      { "actors": {}, "title": {"format": "text","max_phrases": 2,"pre_tag": "","post_tag": ""} }

    • partial — (Boolean)

      Enables partial results to be returned if one or more index partitions are unavailable. When your search index is partitioned across multiple search instances, by default Amazon CloudSearch only returns results if every partition can be queried. This means that the failure of a single search instance can result in 5xx (internal server) errors. When you enable partial results, Amazon CloudSearch returns whatever results are available and includes the percentage of documents searched in the search results (percent-searched). This enables you to more gracefully degrade your users' search experience. For example, rather than displaying no results, you could display the partial results and a message indicating that the results might be incomplete due to a temporary system outage.

    • query — (String)

      Specifies the search criteria for the request. How you specify the search criteria depends on the query parser used for the request and the parser options specified in the queryOptions parameter. By default, the simple query parser is used to process requests. To use the structured, lucene, or dismax query parser, you must also specify the queryParser parameter.

      For more information about specifying search criteria, see Searching Your Data in the Amazon CloudSearch Developer Guide.

    • queryOptions — (String)

      Configures options for the query parser specified in the queryParser parameter. You specify the options in JSON using the following form {"OPTION1":"VALUE1","OPTION2":VALUE2"..."OPTIONN":"VALUEN"}.

      The options you can configure vary according to which parser you use:

      • defaultOperator: The default operator used to combine individual terms in the search string. For example: defaultOperator: 'or'. For the dismax parser, you specify a percentage that represents the percentage of terms in the search string (rounded down) that must match, rather than a default operator. A value of 0% is the equivalent to OR, and a value of 100% is equivalent to AND. The percentage must be specified as a value in the range 0-100 followed by the percent (%) symbol. For example, defaultOperator: 50%. Valid values: and, or, a percentage in the range 0%-100% (dismax). Default: and (simple, structured, lucene) or 100 (dismax). Valid for: simple, structured, lucene, and dismax.
      • fields: An array of the fields to search when no fields are specified in a search. If no fields are specified in a search and this option is not specified, all text and text-array fields are searched. You can specify a weight for each field to control the relative importance of each field when Amazon CloudSearch calculates relevance scores. To specify a field weight, append a caret (^) symbol and the weight to the field name. For example, to boost the importance of the title field over the description field you could specify: "fields":["title5","description"]. Valid values: The name of any configured field and an optional numeric value greater than zero. Default: All text and text-array fields. Valid for: simple, structured, lucene, and dismax.
      • operators: An array of the operators or special characters you want to disable for the simple query parser. If you disable the and, or, or not operators, the corresponding operators (+, |, -) have no special meaning and are dropped from the search string. Similarly, disabling prefix disables the wildcard operator (*) and disabling phrase disables the ability to search for phrases by enclosing phrases in double quotes. Disabling precedence disables the ability to control order of precedence using parentheses. Disabling near disables the ability to use the ~ operator to perform a sloppy phrase search. Disabling the fuzzy operator disables the ability to use the ~ operator to perform a fuzzy search. escape disables the ability to use a backslash (\) to escape special characters within the search string. Disabling whitespace is an advanced option that prevents the parser from tokenizing on whitespace, which can be useful for Vietnamese. (It prevents Vietnamese words from being split incorrectly.) For example, you could disable all operators other than the phrase operator to support just simple term and phrase queries: "operators":["and","not","or", "prefix"]. Valid values: and, escape, fuzzy, near, not, or, phrase, precedence, prefix, whitespace. Default: All operators and special characters are enabled. Valid for: simple.
      • phraseFields: An array of the text or text-array fields you want to use for phrase searches. When the terms in the search string appear in close proximity within a field, the field scores higher. You can specify a weight for each field to boost that score. The phraseSlop option controls how much the matches can deviate from the search string and still be boosted. To specify a field weight, append a caret (^) symbol and the weight to the field name. For example, to boost phrase matches in the title field over the abstract field, you could specify: "phraseFields":["title3", "plot"] Valid values: The name of any text or text-array field and an optional numeric value greater than zero. Default: No fields. If you don't specify any fields with phraseFields, proximity scoring is disabled even if phraseSlop is specified. Valid for: dismax.
      • phraseSlop: An integer value that specifies how much matches can deviate from the search phrase and still be boosted according to the weights specified in the phraseFields option; for example, phraseSlop: 2. You must also specify phraseFields to enable proximity scoring. Valid values: positive integers. Default: 0. Valid for: dismax.
      • explicitPhraseSlop: An integer value that specifies how much a match can deviate from the search phrase when the phrase is enclosed in double quotes in the search string. (Phrases that exceed this proximity distance are not considered a match.) For example, to specify a slop of three for dismax phrase queries, you would specify "explicitPhraseSlop":3. Valid values: positive integers. Default: 0. Valid for: dismax.
      • tieBreaker: When a term in the search string is found in a document's field, a score is calculated for that field based on how common the word is in that field compared to other documents. If the term occurs in multiple fields within a document, by default only the highest scoring field contributes to the document's overall score. You can specify a tieBreaker value to enable the matches in lower-scoring fields to contribute to the document's score. That way, if two documents have the same max field score for a particular term, the score for the document that has matches in more fields will be higher. The formula for calculating the score with a tieBreaker is (max field score) + (tieBreaker) * (sum of the scores for the rest of the matching fields). Set tieBreaker to 0 to disregard all but the highest scoring field (pure max): "tieBreaker":0. Set to 1 to sum the scores from all fields (pure sum): "tieBreaker":1. Valid values: 0.0 to 1.0. Default: 0.0. Valid for: dismax.
    • queryParser — (String)

      Specifies which query parser to use to process the request. If queryParser is not specified, Amazon CloudSearch uses the simple query parser.

      Amazon CloudSearch supports four query parsers:

      • simple: perform simple searches of text and text-array fields. By default, the simple query parser searches all text and text-array fields. You can specify which fields to search by with the queryOptions parameter. If you prefix a search term with a plus sign (+) documents must contain the term to be considered a match. (This is the default, unless you configure the default operator with the queryOptions parameter.) You can use the - (NOT), | (OR), and * (wildcard) operators to exclude particular terms, find results that match any of the specified terms, or search for a prefix. To search for a phrase rather than individual terms, enclose the phrase in double quotes. For more information, see Searching for Text in the Amazon CloudSearch Developer Guide.
      • structured: perform advanced searches by combining multiple expressions to define the search criteria. You can also search within particular fields, search for values and ranges of values, and use advanced options such as term boosting, matchall, and near. For more information, see Constructing Compound Queries in the Amazon CloudSearch Developer Guide.
      • lucene: search using the Apache Lucene query parser syntax. For more information, see Apache Lucene Query Parser Syntax.
      • dismax: search using the simplified subset of the Apache Lucene query parser syntax defined by the DisMax query parser. For more information, see DisMax Query Parser Syntax.
      Possible values include:
      • "simple"
      • "structured"
      • "lucene"
      • "dismax"
    • return — (String)

      Specifies the field and expression values to include in the response. Multiple fields or expressions are specified as a comma-separated list. By default, a search response includes all return enabled fields (_all_fields). To return only the document IDs for the matching documents, specify _no_fields. To retrieve the relevance score calculated for each document, specify _score.

    • size — (Integer)

      Specifies the maximum number of search hits to include in the response.

    • sort — (String)

      Specifies the fields or custom expressions to use to sort the search results. Multiple fields or expressions are specified as a comma-separated list. You must specify the sort direction (asc or desc) for each field; for example, year desc,title asc. To use a field to sort results, the field must be sort-enabled in the domain configuration. Array type fields cannot be used for sorting. If no sort parameter is specified, results are sorted by their default relevance scores in descending order: _score desc. You can also sort by document ID (_id asc) and version (_version desc).

      For more information, see Sorting Results in the Amazon CloudSearch Developer Guide.

    • start — (Integer)

      Specifies the offset of the first search hit you want to return. Note that the result set is zero-based; the first result is at index 0. You can specify either the start or cursor parameter in a request, they are mutually exclusive.

      For more information, see Paginating Results in the Amazon CloudSearch Developer Guide.

    • stats — (String)

      Specifies one or more fields for which to get statistics information. Each specified field must be facet-enabled in the domain configuration. The fields are specified in JSON using the form:

      {"FIELD-A":{},"FIELD-B":{}}

      There are currently no options supported for statistics.

Callback (callback):

  • function(err, data) { ... }

suggest(params = {}, callback) ⇒ AWS.Request

Retrieves autocomplete suggestions for a partial query string. You can use suggestions enable you to display likely matches before users finish typing. In Amazon CloudSearch, suggestions are based on the contents of a particular text field. When you request suggestions, Amazon CloudSearch finds all of the documents whose values in the suggester field start with the specified query string. The beginning of the field must match the query string to be considered a match.

For more information about configuring suggesters and retrieving suggestions, see Getting Suggestions in the Amazon CloudSearch Developer Guide.

The endpoint for submitting Suggest requests is domain-specific. You submit suggest requests to a domain's search endpoint. To get the search endpoint for your domain, use the Amazon CloudSearch configuration service DescribeDomains action. A domain's endpoints are also displayed on the domain dashboard in the Amazon CloudSearch console.

Examples:

Calling the suggest operation

var params = {
  query: 'STRING_VALUE', /* required */
  suggester: 'STRING_VALUE', /* required */
  size: 0
};
cloudsearchdomain.suggest(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • query — (String)

      Specifies the string for which you want to get suggestions.

    • suggester — (String)

      Specifies the name of the suggester to use to find suggested matches.

    • size — (Integer)

      Specifies the maximum number of suggestions to return.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • status — (map)

        The status of a SuggestRequest. Contains the resource ID (rid) and how long it took to process the request (timems).

        • timems — (Integer)

          How long it took to process the request, in milliseconds.

        • rid — (String)

          The encrypted resource ID for the request.

      • suggest — (map)

        Container for the matching search suggestion information.

        • query — (String)

          The query string specified in the suggest request.

        • found — (Integer)

          The number of documents that were found to match the query string.

        • suggestions — (Array<map>)

          The documents that match the query string.

          • suggestion — (String)

            The string that matches the query string specified in the SuggestRequest.

          • score — (Integer)

            The relevance score of a suggested match.

          • id — (String)

            The document ID of the suggested document.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

uploadDocuments(params = {}, callback) ⇒ AWS.Request

Posts a batch of documents to a search domain for indexing. A document batch is a collection of add and delete operations that represent the documents you want to add, update, or delete from your domain. Batches can be described in either JSON or XML. Each item that you want Amazon CloudSearch to return as a search result (such as a product) is represented as a document. Every document has a unique ID and one or more fields that contain the data that you want to search and return in results. Individual documents cannot contain more than 1 MB of data. The entire batch cannot exceed 5 MB. To get the best possible upload performance, group add and delete operations in batches that are close the 5 MB limit. Submitting a large volume of single-document batches can overload a domain's document service.

The endpoint for submitting UploadDocuments requests is domain-specific. To get the document endpoint for your domain, use the Amazon CloudSearch configuration service DescribeDomains action. A domain's endpoints are also displayed on the domain dashboard in the Amazon CloudSearch console.
