  • Method Details

    • getIndexName

      public String getIndexName()
      Gets the name of the Azure Cognitive Search index.
      Returns:
      the indexName value.
    • getEndpoint

      public String getEndpoint()
      Gets the endpoint for the Azure Cognitive Search service.
      Returns:
      the endpoint value.
    • uploadDocuments

      public Mono<IndexDocumentsResult> uploadDocuments(Iterable<?> documents)
      Uploads a collection of documents to the target index.

      Code Sample

      Upload dynamic SearchDocument.

       SearchDocument searchDocument = new SearchDocument();
       searchDocument.put("hotelId", "1");
       searchDocument.put("hotelName", "test");
       SEARCH_ASYNC_CLIENT.uploadDocuments(Collections.singletonList(searchDocument))
           .subscribe(result -> {
               for (IndexingResult indexingResult : result.getResults()) {
                   System.out.printf("Does document with key %s upload successfully? %b%n",
                       indexingResult.getKey(), indexingResult.isSucceeded());
               }
           });
       
      Parameters:
      documents - collection of documents to upload to the target Index.
      Returns:
      The result of the document indexing actions.
      Throws:
      IndexBatchException - If an indexing action fails but other actions succeed and modify the state of the index. This can happen when the Search Service is under heavy indexing load. It is important to explicitly catch this exception and check the return value IndexBatchException.getIndexingResults(). The indexing result reports the status of each indexing action in the batch, making it possible to determine the state of the index after a partial failure.

    • uploadDocumentsWithResponse

      public Mono<com.azure.core.http.rest.Response<IndexDocumentsResult>> uploadDocumentsWithResponse(Iterable<?> documents, IndexDocumentsOptions options)
      Uploads a collection of documents to the target index.

      Code Sample

      Upload dynamic SearchDocument.

       SearchDocument searchDocument = new SearchDocument();
       searchDocument.put("hotelId", "1");
       searchDocument.put("hotelName", "test");
       searchAsyncClient.uploadDocumentsWithResponse(Collections.singletonList(searchDocument), null)

               System.out.println("The status code of the response is " + resultResponse.getStatusCode());
               for (IndexingResult indexingResult : resultResponse.getValue().getResults()) {
                   System.out.printf("Does document with key %s upload successfully? %b%n", indexingResult.getKey(),
                       indexingResult.isSucceeded());

      IndexBatchException - If an indexing action fails but other actions succeed and modify the state of the index. This can happen when the Search Service is under heavy indexing load. It is important to explicitly catch this exception and check the return value IndexBatchException.getIndexingResults(). The indexing result reports the status of each indexing action in the batch, making it possible to determine the state of the index after a partial failure.

    • mergeDocuments

      public Mono<IndexDocumentsResult> mergeDocuments(Iterable<?> documents)
      Merges a collection of documents with existing documents in the target index.

      If the type of the document contains non-nullable primitive-typed properties, these properties may not merge correctly. If you do not set such a property, it will automatically take its default value (for example, 0 for int or false for boolean), which will override the value of the property currently stored in the index, even if this was not your intent. For this reason, it is strongly recommended that you always declare primitive-typed properties with their class equivalents (for example, an integer property should be of type Integer instead of int).

      Code Sample

      Merge dynamic SearchDocument.

       SearchDocument searchDocument = new SearchDocument();
       searchDocument.put("hotelName", "merge");
       SEARCH_ASYNC_CLIENT.mergeDocuments(Collections.singletonList(searchDocument))
           .subscribe(result -> {
               for (IndexingResult indexingResult : result.getResults()) {
                   System.out.printf("Does document with key %s merge successfully? %b%n", indexingResult.getKey(),
                       indexingResult.isSucceeded());
               }
           });
       
      Parameters:
      documents - collection of documents to be merged
      Returns:
      document index result
      Throws:
      IndexBatchException - If an indexing action fails but other actions succeed and modify the state of the index. This can happen when the Search Service is under heavy indexing load. It is important to explicitly catch this exception and check the return value IndexBatchException.getIndexingResults(). The indexing result reports the status of each indexing action in the batch, making it possible to determine the state of the index after a partial failure.

    • mergeOrUploadDocuments

      public Mono<IndexDocumentsResult> mergeOrUploadDocuments(Iterable<?> documents)
