Multiple queries in E v5.6 REST high level client

How can I have multiple query in Search API in elasticsearch v5.6 in rest high level client? I need to have OR and AND queries in the search query. I’ve been using searchSourceBuilder, it only has one matchQuery.

QueryBuilder matchQueryBuilder = QueryBuilders.matchQuery(field, query);

Thanks in advance!

Answer

You can use something like:

BoolQueryBuilder finalQuery = QueryBuilders.boolQuery();

For OR clauses you can use:

finalQuery.should().add(your query);

For AND clauses you can use:

finalQuery.must().add(your query);

You can link them however you want, and you can nest them as the logic dictates.
