Update Document(s)

Update a JSON document or an array of JSON documents (bulk), each consisting of arbitrary key-value pairs to the index with the specified apikey and index_id, and return the number of indexed docs. Update document is a combination of delete_document and index_document. All current limitations of delete_document apply. Update documents enables true real-time search (as opposed to near realtime.search): When in query_index the parameter realtime is set to true then indexed, but uncommitted documents are immediately included in the search results, without requiring a commit or refresh. Therefore a explicit commit_index is almost never required, as it is invoked automatically after 64k documents are indexed per shard or on close_index for persistence.
