mergeDocuments

public 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");
 IndexDocumentsResult result = SEARCH_CLIENT.mergeDocuments(Collections.singletonList(searchDocument));
 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

mergeDocumentsWithResponse

public Response mergeDocumentsWithResponse(Iterable documents, IndexDocumentsOptions options, Context context)

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", "test");
 Response<IndexDocumentsResult> resultResponse = SEARCH_CLIENT.mergeDocumentsWithResponse(
     Collections.singletonList(searchDocument), null, new Context(KEY_1, VALUE_1));
 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 merge successfully? %b%n", indexingResult.getKey(),
         indexingResult.isSucceeded());
 }

Parameters:

documents - collection of documents to be merged.

options - Options that allow specifying document indexing behavior.

context - additional context that is passed through the Http pipeline during the service call

Returns:

response containing the document index result.

mergeOrUploadDocuments

public IndexDocumentsResult mergeOrUploadDocuments(Iterable documents)

This action behaves like merge if a document with the given key already exists in the index. If the document does not exist, it behaves like upload with a new document.

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 or upload dynamic SearchDocument.

SearchDocument searchDocument = new SearchDocument();
 searchDocument.put("hotelId", "1");
 searchDocument.put("hotelName", "test");
 IndexDocumentsResult result = SEARCH_CLIENT.mergeOrUploadDocuments(Collections.singletonList(searchDocument));
 for (IndexingResult indexingResult : result.getResults()) {
     System.out.printf("Does document with key %s mergeOrUpload successfully? %b%n", indexingResult.getKey(),
         indexingResult.isSucceeded());
 }

Parameters:

documents - collection of documents to be merged, if exists, otherwise uploaded

Returns:

document index result

mergeOrUploadDocumentsWithResponse

public Response mergeOrUploadDocumentsWithResponse(Iterable documents, IndexDocumentsOptions options, Context context)

This action behaves like merge if a document with the given key already exists in the index. If the document does not exist, it behaves like upload with a new document.

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 or upload dynamic SearchDocument.

SearchDocument searchDocument = new SearchDocument();
 searchDocument.put("hotelId", "1");
 searchDocument.put("hotelName", "test");

search

public SearchPagedIterable search(String searchText)

Searches for documents in the Azure Cognitive Search index.

If searchText is set to null or "*" all documents will be matched, see simple query syntax in Azure Cognitive Search for more information about search query syntax.

The SearchPagedIterable will iterate through search result pages until all search results are returned. Each page is determined by the $skip and $top values and the Search service has a limit on the number of documents that can be skipped, more information about the $skip limit can be found at Search Documents REST API and reading the $skip description. If the total number of results exceeds the $skip limit the SearchPagedIterable won't prevent you from exceeding the $skip limit. To prevent exceeding the limit you can track the number of documents returned and stop requesting new pages when the limit is reached.

Code Sample

Search text from documents in service.

SearchPagedIterable searchPagedIterable = SEARCH_CLIENT.search("searchText");
 System.out.printf("There are around %d results.", searchPagedIterable.getTotalCount());

 long numberOfDocumentsReturned = 0;
 for (SearchPagedResponse resultResponse: searchPagedIterable.iterableByPage()) {
     System.out.println("The status code of the response is " + resultResponse.getStatusCode());
     numberOfDocumentsReturned += resultResponse.getValue().size();
     resultResponse.getValue().forEach(searchResult -> {
         for (Map.Entry<String, Object> keyValuePair: searchResult
             .getDocument(SearchDocument.class).entrySet()) {
             System.out.printf("Document key %s, document value %s", keyValuePair.getKey(),
                 keyValuePair.getValue());
         }
     });

     if (numberOfDocumentsReturned >= SEARCH_SKIP_LIMIT) {
         // Reached the $skip limit, stop requesting more documents.
         break;
     }
 }

Parameters:

searchText - A full-text search query expression.

Returns:

A SearchPagedIterable that iterates over SearchResult objects and provides access to the SearchPagedResponse object for each page containing HTTP response and count, facet, and coverage information.

search
