compound queries in elasticsearch, java api

Question

How to make compound query, as example I need to find geojson data with some properties (these properties is set in search query) within some polygon?

I know there are the GeoPolygonQueryBuilder and the BoolQueryBuilder for these kind of requests, but how to use them together in a single request to fetch data from ES?

Thanks!

This is a shot in the dark, because your question is lacking a minimal, reproducible example or even pseudo-code. If you are asking how to write a query that combines two sub queries, use the BoolQueryBuilder and provide multiple mandatory sub queries:

final BoolQueryBuilder query = new BoolQueryBuilder()
        .must(new GeoPolygonQueryBuilder(
                   "geo_field",
                   List.of(new GeoPoint(14, 50), …)))
        .must(new GeoPolygonQueryBuilder(
                   "geo_field",
                   List.of(new GeoPoint(14, 50), …)));

BoolQueryBuilder has additional methods such as mustNot, should, or filter.
