Hi @suresh_chaudhari

I think I already answered a similar question, here's an example using RHLC. I sort by name in this example

If you are using the new java client, use the example to adapt.


    //FIRST REQUEST
    SearchSourceBuilder builder = new SearchSourceBuilder();
    builder.sort(SortBuilders.fieldSort("name").order(SortOrder.DESC));
    builder.size(2);
    builder.query(QueryBuilders.matchAllQuery());

    SearchRequest searchRequest = new SearchRequest();
    searchRequest.indices("idx_movies_suggest");
    searchRequest.source(builder);
    var response = client.search(searchRequest, RequestOptions.DEFAULT);

    System.out.println(response);

    //SECOND REQUEST WITH SEARCH AFTER
    builder = new SearchSourceBuilder();
    builder.sort(SortBuilders.fieldSort("name").order(SortOrder.DESC));
    builder.size(2);
    builder.query(QueryBuilders.matchAllQuery());

    searchRequest = new SearchRequest();
    searchRequest.indices("idx_movies_suggest");
    searchRequest.source(builder);

    //USING SEARCH AFTER
    Object[] arrSearchAfter = new Object[]{"batman"};
    builder.searchAfter(arrSearchAfter);

    searchRequest = new SearchRequest();
    searchRequest.indices("idx_movies_suggest");
    searchRequest.source(builder);
    response = client.search(searchRequest, RequestOptions.DEFAULT);

    System.out.println(response);
