/**
* Service Description: Service for search.
*
* <p>This feature is only available for users who have Retail Search enabled. Please enable Retail
* Search on Cloud Console before using this feature.
*
* <p>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:
*
* <pre>{@code
* // 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()
* .setPlacement("placement1792938725")
* .setBranch(
* BranchName.of("[PROJECT]", "[LOCATION]", "[CATALOG]", "[BRANCH]").toString())
* .setQuery("query107944136")
* .setVisitorId("visitorId1880545833")
* .setUserInfo(UserInfo.newBuilder().build())
* .setPageSize(883849137)
* .setPageToken("pageToken873572522")
* .setOffset(-1019779949)
* .setFilter("filter-1274492040")
* .setCanonicalFilter("canonicalFilter-722283124")
* .setOrderBy("orderBy-1207110587")
* .addAllFacetSpecs(new ArrayList<SearchRequest.FacetSpec>())
* .setDynamicFacetSpec(SearchRequest.DynamicFacetSpec.newBuilder().build())
* .setBoostSpec(SearchRequest.BoostSpec.newBuilder().build())
* .setQueryExpansionSpec(SearchRequest.QueryExpansionSpec.newBuilder().build())
* .addAllVariantRollupKeys(new ArrayList<String>())
* .addAllPageCategories(new ArrayList<String>())
* .setPersonalizationSpec(SearchRequest.PersonalizationSpec.newBuilder().build())
* .putAllLabels(new HashMap<String, String>())
* .setSpellCorrectionSpec(SearchRequest.SpellCorrectionSpec.newBuilder().build())
* .build();
* for (SearchResponse.SearchResult element : searchServiceClient.search(request).iterateAll()) {
* // doThingsWith(element);
* }
* }
* }</pre>
*
* <p>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().
*
* <p>The surface of this class includes several types of Java methods for each of the API's
* methods:
*
* <ol>
* <li>A "flattened" method. With this type of method, the fields of the request type have been
* converted into function parameters. It may be the case that not all fields are available as
* parameters, and not every API method will have a flattened method entry point.
* <li>A "request object" method. This type of method only takes one parameter, a request object,
* which must be constructed before the call. Not every API method will have a request object
* method.
* <li>A "callable" method. This type of method takes no parameters and returns an immutable API
* callable object, which can be used to initiate calls to the service.
* </ol>
*
* <p>See the individual methods for example code.
*
* <p>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.
*
* <p>This class can be customized by passing in a custom instance of SearchServiceSettings to
* create(). For example:
*
* <p>To customize credentials:
*
* <pre>{@code
* // 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);
* }</pre>
*
* <p>To customize the endpoint:
*
* <pre>{@code
* // 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);
* }</pre>
*
* <p>To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
* the wire:
*
* <pre>{@code
* // 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()
* .setTransportChannelProvider(
* SearchServiceSettings.defaultHttpJsonTransportProviderBuilder().build())
* .build();
* SearchServiceClient searchServiceClient = SearchServiceClient.create(searchServiceSettings);
* }</pre>
*
* <p>Please refer to the GitHub repository's samples for more quickstart code snippets.
