You can pass a search “timeout” in the request body or in the uri request. If the search request times out before collecting all results, the partial results will be returned. Here’s a uri request example for 10 seconds (units are in milliseconds): http://localhost:9200/_search?timeout=10000 If you set the timeout low enough, the returned json will … Read more
In elasticsearch, it’s not possible to paginate an aggregation. The query will not give accurate results if size is specified. So, the only way to do sorting and pagination is to give size 0 and return all the documents and then, get the required results by accumulating all the results in a list for further … Read more
