966	[patch] add 'not'-variants to some lookup kwargs	hugo	Adrian Holovaty	"Currently there are no 'inotcontains', 'notcontains', 'notstartswith', 'notendswith' queries which makes it awkward if you want to build a query that searches for all stuff that includes 'foo' but doesn't include 'bar' - you need to fetch IDs and filter IDs based on those results yourself.

This could be done in two ways: either just add those query lookup kwargs to the backends (mapping them to the matching NOT LIKE clauses) or enhance the AND/OR combinator syntax by introducing __not__ handling (creating a Qnot object that will render as NOT(condition) in the SQL). The first version is much easier to do and fit's nicely into the current kwarg-based query syntax, so I would opt for that version."	enhancement	closed	Core (Other)		normal	fixed			Unreviewed	1	0	0	0	0	0
