Converts arbitrarily complicated user entered query strings to a haystack query object.

###Usage

from haystack_queryparser import ParseSQ

Also provides or_parser and and_parser which can be directly used with a query

parser = ParseSQ() 
sq_object = parser.parse(query)

takes a AND or OR operator to use as default optionally.

###Input Input should be a string.This the query.

###Output Output is a SQ(haystack.query.SQ) object. This can be passed to SearchQuerySet.filter and the query will be applied

###Test To run the test you need to be in the django environment.So you can do something like this:

$ python manage.py shell
>>> import haystack_queryparser.tests as test
>>> tests.main()
test_operators (modules.haystack_queryparser2.tests.SimpleTest) ... ok
test_parse (modules.haystack_queryparser2.tests.SimpleTest) ... ok
test_parse_with_new_default (modules.haystack_queryparser2.tests.SimpleTest) ... ok
