treat parenthesized subqueries the same for boolean and probabilistic fields
|Reported by:||bremner||Owned by:||Olly Betts|
currently foo:(bar blah) is either parsed as foo:bar OP foo:blah for probabilistic fields but as "foo:(bar" OP blah for boolean fields. This is pretty surprising. I think it would better to in both cases parse the subquery with the default prefix foo.
