Would you explain me the boolQuery?

Hi all.

First,
QueryBuilders.boolQuery().must(QueryBuilders.termsQuery("search_field",
"term1", "term2").minimumMatch(2));

Second,
QueryBuilders.boolQuery().should(QueryBuilders.termsQuery("search_field",
"term1", "term2").minimumMatch(2));

I think, a search result will be same which are first and second case.
What do you think about it?

I will look forward your comment.

Thank you.

Hey,

Look here: Elasticsearch Platform — Find real-time answers at scale | Elastic

In a boolean query with no must clauses, one or more should clauses must match a document.

So with only one should clause and no must, the should clause is equivalent to the must clause.
