-
Run resource-intensive queries asynchronously with asynchronous search.
-
Search for k-nearest neighbors with k-NN search.
-
Abstract OpenSearch queries into search templates.
-
Paginate and sort search results, highlight search terms, and use the autocomplete and did-you-mean functionality.
-
Rewrite queries with Querqy.
