Which Lucene version and which query parser is this? Can you provide a test case/ code sample? I just tried with StandardQueryParser and for:
sqp.setDefaultOperator(StandardQueryConfigHandler.Operator.AND); dump(sqp.parse("foo AND bar OR baz", "field_a")); sqp.setDefaultOperator(StandardQueryConfigHandler.Operator.OR); dump(sqp.parse("foo AND bar OR baz", "field_a")); I get the same result: BooleanQuery: +field_a:foo +field_a:bar field_a:baz Dawid On Wed, Nov 9, 2016 at 6:04 PM, Pawel Rog <ppp.pawel...@gmail.com> wrote: > Hi Eric, > Thank you for your email. > I understand that Lucene queries are not in boolean logic.
