How to create nested boolean query with lucene API (a AND (b OR c))?

Question

I have an indexed object with three fields (userId, title, description). I want to find all objects of a specific user where the title OR the description contains a given ke

Answer 1

I believe that you'll need to use the Query.mergeBooleanQueries method in order to create a single query that is the effective OR of the first two.

So something like this at line 3:

Query nameOrDescQuery = Query.mergeBooleanQueries(new Query[] { nameQuery, descQuery });

and then create a new BooleanClause over this, rather than the individual clauses.

This should ensure you get the OR logic on your name/desc filters rather than the current AND logic.
