Now available – New query features in Azure Search

Azure Search has two new features that are now generally available. The autocomplete API feature searches an existing index to suggest terms to complete a partial query. The synonyms functionality feature allows for Azure Search to not only return results matching the query terms typed into the search box, but to also return results that match synonyms of the query terms that you've defined.
