Class SearchServiceClient (0.49.0)

GitHub RepositoryProduct Reference

Service Description: Service for search.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (SearchServiceClient searchServiceClient = SearchServiceClient.create()) {
   SearchRequest request =
       SearchRequest.newBuilder()
           .setServingConfig(
               ServingConfigName.ofProjectLocationDataStoreServingConfigName(
                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[SERVING_CONFIG]")
                   .toString())
           .setBranch(
               BranchName.ofProjectLocationDataStoreBranchName(
                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[BRANCH]")
                   .toString())
           .setQuery("query107944136")
           .setImageQuery(SearchRequest.ImageQuery.newBuilder().build())
           .setPageSize(883849137)
           .setPageToken("pageToken873572522")

           .setSpellCorrectionSpec(SearchRequest.SpellCorrectionSpec.newBuilder().build())
           .setUserPseudoId("userPseudoId-1155274652")
           .setContentSearchSpec(SearchRequest.ContentSearchSpec.newBuilder().build())
           .setEmbeddingSpec(SearchRequest.EmbeddingSpec.newBuilder().build())
           .setRankingExpression("rankingExpression2110320494")
           .setSafeSearch(true)
           .putAllUserLabels(new HashMap<String, String>())
           .setNaturalLanguageQueryUnderstandingSpec(
               SearchRequest.NaturalLanguageQueryUnderstandingSpec.newBuilder().build())
           .setSearchAsYouTypeSpec(SearchRequest.SearchAsYouTypeSpec.newBuilder().build())
           .setSession(
               SessionName.ofProjectLocationDataStoreSessionName(
                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[SESSION]")
                   .toString())
           .setSessionSpec(SearchRequest.SessionSpec.newBuilder().build())
           .build();
   for (SearchResponse.SearchResult element : searchServiceClient.search(request).iterateAll()) {
     // doThingsWith(element);
   }
 }

Note: close() needs to be called on the SearchServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

Search

Performs a search.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • search(SearchRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • searchPagedCallable()

  • searchCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of SearchServiceSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SearchServiceSettings searchServiceSettings =
     SearchServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SearchServiceClient searchServiceClient = SearchServiceClient.create(searchServiceSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SearchServiceSettings searchServiceSettings =
     SearchServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 SearchServiceClient searchServiceClient = SearchServiceClient.create(searchServiceSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SearchServiceSettings searchServiceSettings =
     SearchServiceSettings.newHttpJsonBuilder().build();
 SearchServiceClient searchServiceClient = SearchServiceClient.create(searchServiceSettings);
