I am looking for a string parser that works kind of like Google's or
Gmail's advanced search capabilities. So it would turn something like this:
(subject:"hi there" from:[tim, tom, -fred]) or (subject:foobar from:sam)
into a python structure that could be used. I don't really care so much
about the search syntax except that easy and intuitive is best for
users. Does something like this exist?
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)])])
