API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

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.

For more information about formatting your data for Amazon CloudSearch, see Preparing Your Data in the Amazon CloudSearch Developer Guide. For more information about uploading data for indexing, see Uploading Data in the Amazon CloudSearch Developer Guide.
