Hey folks, I'm experiencing some strange query behaviour, and it isn't immediately clear to me why this wouldn happen. The definition of the query syntax on the wiki is a bit fuzzy, so my interpretation of the syntax might be off.
This query does work (no results, when results are expected). (-someField:Foo) AND (otherField: (Bar OR Baz)) With debug enabled, Solr interprets the query as +(-someField:Foo) +(otherField:Bar otherField:Baz) This query DOES work, results are returned. -someField:Foo +(otherField:Bar otherField:Baz) With debug enabled: -someField:Foo +(otherField:Bar otherField:Baz) The only difference between these queries is the presence of parantheses around the field with a single NOT condition. From a boolean point of view, they are equivalent. To make matters stranger, if I add a *:* clause to the NOT field, everything works again. (-someField:Foo AND *:*) AND (otherField: (Bar OR Baz)) and -someField:Foo AND *:* AND (otherField: (Bar OR Baz)) both work. Is this is query parser bug? Or are parenthesized groups with a single negated expression not supported? :-/ I've only tested this on 5.5.4 using the default query parser, I don't have access to any other versions at the moment. Thanks for any insights, - Bram
