The Whoosh search library uses pyparsing to parse its queries. It does not
handle the [] brackets, but it handles the rest. I am sure that Matt Chaput
would accept a contribution of such an enhancement, though.

In [9]: from whoosh import qparser
In [10]: p = qparser.QueryParser('body')
In [11]: p.parse(u'subject:hi there or (subject:foobar from:sam)')
Out[11]: Or([Phrase(u'subject', [u'hi', u'there']), And([Term(u'subject',
u'foobar', boost=1.0), Term(u'from', u'sam', boost=1.0)])])
