I have no idea what is your
queryset filter criteria but this is how you
merge multiple queryset for same model
q1 = Post.object.filter(author_id=55)
q2 = Post.object.filter(publisher_id=1095)
result = q1|q2
result = Post.objects.filter(Q(author_id=55) | Q(publisher_id=1095))
sql equivalent of
WHERE author_id = '55' OR publisher_id = '1095'
queryset are lazy, don't forget to check
sql genereated using
.query() to figure out what django ORM is doing.
