Amazon CloudSearch is a fully-managed service in the cloud that makes it easy to set up, manage, and scale a search solution for your website or application.
With Amazon CloudSearch you can search large collections of data such as web pages, document files, forum posts, or product information. You can quickly add search capabilities without having to become a search expert or worry about hardware provisioning, setup, and maintenance. As your volume of data and traffic fluctuates, Amazon CloudSearch scales to meet your needs.
This document describes the Amazon CloudSearch 2013-01-01 API. If you have 2011-02-01 search domains and need to reference the old documentation, you can download a PDF of the 2011-02-01 Developer Guide.
You can use Amazon CloudSearch to index and search both structured data and plain text. Amazon CloudSearch features:
Full text search with language-specific text processing
You can get search results in JSON or XML, sort and filter results based on field values, and sort results alphabetically, numerically, or according to custom expressions.
To build a search solution with Amazon CloudSearch, you take the following steps:
Create and configure a search domain. A search domain includes your searchable data and the search instances that handle your search requests. If you have multiple collections of data that you want to make searchable, you can create multiple search domains.
Upload the data you want to search to your domain. Amazon CloudSearch indexes your data and deploys the search index to one or more search instances.
Search your domain. You send a search request to your domain's search endpoint as an HTTP/HTTPS GET request.
For a high-level overview of Amazon CloudSearch, service highlights, and pricing information, see the Amazon CloudSearch detail page. If you are ready to start using Amazon CloudSearch, you should begin with Getting Started with Amazon CloudSearch.
You can interact with Amazon CloudSearch through the AWS Management Console, AWS SDKs, or AWS CLI. While you can also submit API requests directly to Amazon CloudSearch, the SDKs and AWS CLI automatically sign your requests as needed and provide centralized tools for interacting with Amazon CloudSearch domains in conjunction with other AWS services. For information about the AWS SDKs, see Tools for Amazon Web Services. For information about installing and using the AWS CLI, see the AWS Command Line Interface User Guide.
For more information about configuring and managing your search domains, getting your data into Amazon CloudSearch, submitting search requests, and processing the responses, see:

You can access Amazon CloudSearch through the Amazon CloudSearch console, the AWS SDKs, or the AWS CLI.
The Amazon CloudSearch console enables you to easily create, configure, and monitor your search domains, upload documents, and run test searches. Using the console is the easiest way to get started with Amazon CloudSearch and provides a central command center for ongoing management of your search domains.
The AWS SDKs support all of the Amazon CloudSearch API operations, making it easy to manage and interact with your search domain's using your preferred technology. The SDKs automatically sign requests as needed using your AWS credentials.
The AWS CLI wraps all of the Amazon CloudSearch API operations to provide a simple way to create and configure search domains, upload the data you want to search, and submit search requests. The AWS CLI automatically signs requests as needed using your AWS credentials.
The standalone Amazon CloudSearch command line tools provide higher level tools for generating document batches and automatically configuring indexing options based on the contents of a batch. For more information about installing the Amazon CloudSearch tools, see the Command Line Tool Reference.
Amazon CloudSearch provides regional endpoints for accessing the configuration service and domain-specific endpoints for accessing the search and document services.
You use the configuration service to create and manage your search domains. The region-specific configuration service endpoints are of the form:
cloudsearch.. For example,
cloudsearch.us-east-1.amazonaws.com. For a current list of supported regions, see Regions and Endpoints in the AWS General Reference.
To access the Amazon CloudSearch search and document services, you use separate domain-specific endpoints:
http://doc-—a domain's document service endpoint is used to upload documents.
http://search-—a domain's search endpoint is used to submit search requests.
