def add_should(self, queries):
if isinstance(queries, list):<EOL><INDENT>self._should.extend(queries)<EOL><DEDENT>else:<EOL><INDENT>self._should.append(queries)<EOL><DEDENT>return self<EOL>
Add a query to the "should" clause of the query.

        The Query object will be returned, so calls to this can be chained.
