Reference documentation and code samples for the Discovery Engine v1beta API class SearchRequest.Types.ContentSearchSpec.Types.ChunkSpec.
Specifies the chunk spec to be returned from the search response.
Only available if the
[SearchRequest.ContentSearchSpec.search_result_mode][google.cloud.discoveryengine.v1beta.SearchRequest.ContentSearchSpec.search_result_mode]
is set to
[CHUNKS][google.cloud.discoveryengine.v1beta.SearchRequest.ContentSearchSpec.SearchResultMode.CHUNKS]
