Description: rkQuery
        =======
        
        rkQuery is a library for programmatically building Riak search queries.
        It aims to be easy to use, powerful, and protect from injection attacks
        that would be possible with simple string interpolation.
        
        Installation
        ------------
        
        ::
        
            pip install rkquery
        
        Building Queries
        ----------------
        
        Just start playing around with the ``Q`` object. Literals (that is, raw
        strings in queries) will be escaped if necessary:
        
        ::
        
            >>> from rkquery import Q
            >>> Q("some literal")
            <Q: "some literal">
            >>> Q(field="literal value")
            <Q: field:"literal value">
            >>> Q.not_(blocked="yes")
            <Q: NOT blocked:yes>
        
        You can provide multiple arguments, too. The default query combinator is
        ``AND``:
        
        ::
        
            >>> Q("word1", "word2")
            <Q: word1 AND word2>
            >>> Q(username='foo', password='s3cr3t')
            <Q: password:s3cr3t AND username:foo>
        
        This is just a synonym for ``Q.all()``:
        
        ::
        
            >>> Q.all("word1", "word2")
            <Q: word1 AND word2>
            >>> Q.all(username='foo', password='s3cr3t')
            <Q: password:s3cr3t AND username:foo>
        
        You can construct ``OR`` queries using ``Q.any()``:
        
        ::
        
            >>> Q.any("word1", "word2")
            <Q: word1 OR word2>
            >>> Q.any(username='foo', email='foo@example.com')
            <Q: email:"foo@example.com" OR username:foo>
            >>> Q(field=Q.any("string1", "string2"))
            <Q: field:(string1 OR string2)>
        
        Or by combining existing ``Q`` objects with the bitwise logical
        operators:
        
        ::
        
            >>> Q.any("word1", "word2") & Q("word3")
            <Q: (word1 OR word2) AND word3>
            >>> Q("word3") | Q.all("word1", "word2")
            <Q: (word1 AND word2) OR word3>
            >>> Q.any(email="foo@example.com", username="foo") & Q(password="s3cr3t")
            <Q: (email:"foo@example.com" OR username:foo) AND password:s3cr3t>
        
        There are helpers for negation as well (note that 'none' means 'not
        any'):
        
        ::
        
            >>> Q.none(blocked="yes", cheque_bounced="yes")
            <Q: NOT (blocked:yes OR cheque_bounced:yes)>
            >>> ~Q.any(blocked="yes", cheque_bounced="yes")
            <Q: NOT (blocked:yes OR cheque_bounced:yes)>
        
        You can do range queries with ``Q.range()``:
        
        ::
        
            >>> Q.range("red", "rum")
            <Q: [red TO rum]>
            >>> Q(field=Q.range("red", "rum"))
            <Q: field:[red TO rum]>
        
        Note that the default is an *inclusive* range (square brackets). The
        full set of range queries:
        
        ::
        
            >>> Q.range_inclusive("red", "rum")
            <Q: [red TO rum]>
            >>> Q.range_exclusive("red", "rum")
            <Q: {red TO rum}>
            >>> Q.between("red", "rum")
            <Q: {red TO rum}>
        
        Term boosting is a simple unary operation:
        
        ::
        
            >>> Q("red").boost(5)
            <Q: red^5>
        
        As is proximity:
        
        ::
        
            >>> Q("See spot run").proximity(20)
            <Q: "See spot run"~20>
        
        Running Queries
        ---------------
        
        When you’ve built a query and you want to execute it, just call
        ``unicode()`` on it to get the full query string:
        
        ::
        
            >>> query = Q(field1="foo", field2="bar")
            >>> unicode(query)
            u'field1:foo AND field2:bar'
        
        You can then use the standard Riak client search methods with this
        string.
