17176	Problem when retrieving objects with AND over multiple OR statements	Haisheng HU	nobody	"I'm using Django 1.3 on MongoDB, and met a weird situation.

Project.objects.filter(
        Q(owner=u'A') | Q(owner=u'B'),
        Q(owner=u'C') | Q(owner=u'D'),
    )

The above returned queryset is same to Project.objects.filter(Q(owner=u'C') | Q(owner=u'D')), but not '''None''', as expected. It seems that the first half lookup function was omitted.

Does someone know that it's problem with Django or third-party mongodb-engine libraries? Thanks in ad!"	Bug	closed	Database layer (models, ORM)	1.3	Normal	worksforme			Unreviewed	0	0	0	0	0	0
