Interface AmazonCloudSearchDomain

All Known Subinterfaces:

AmazonCloudSearchDomainAsync

All Known Implementing Classes:

AbstractAmazonCloudSearchDomain, AbstractAmazonCloudSearchDomainAsync, AmazonCloudSearchDomainAsyncClient, AmazonCloudSearchDomainClient

public interface AmazonCloudSearchDomain

Interface for accessing Amazon CloudSearch Domain.

You use the AmazonCloudSearch2013 API to upload documents to a search domain and search those documents.

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

For more information, see the Amazon CloudSearch Developer Guide.

void	setRegion(Region region) An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls.

Method Detail

setEndpoint

void setEndpoint(String endpoint)

Overrides the default endpoint for this client. Callers can use this method to control which AWS region they want to work with.

Callers can pass in just the endpoint or a full URL, including the protocol. If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912

This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:

endpoint - The endpoint or a full URL, including the protocol of the region specific AWS endpoint this client will communicate with.

setRegion

void setRegion(Region region)

An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.

This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:

region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.

Region.getRegion(com.amazonaws.regions.Regions), Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration), Region.isServiceSupported(String)

search

SearchResult search(SearchRequest searchRequest)

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.

Parameters:

searchRequest - Container for the parameters to the Search request.

Returns:

Result of the Search operation returned by the service.

Throws:

SearchException - Information about any problems encountered while processing a search request.

suggest

SuggestResult suggest(SuggestRequest suggestRequest)

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.

Parameters:

suggestRequest - Container for the parameters to the Suggest request.

Returns:

Result of the Suggest operation returned by the service.

Throws:

SearchException - Information about any problems encountered while processing a search request.

uploadDocuments

UploadDocumentsResult uploadDocuments(UploadDocumentsRequest uploadDocumentsRequest)

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.

Parameters:

uploadDocumentsRequest - Container for the parameters to the UploadDocuments request.

Returns:

Result of the UploadDocuments operation returned by the service.

Throws:

DocumentServiceException - Information about any problems encountered while processing an upload request.

shutdown

void shutdown()

Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

getCachedResponseMetadata

ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

Parameters:

request - The originally executed request.

Returns:

The response metadata for the specified request, or null if none is available.
