Django query order depending on starts_with and contains

I try to make a special contains filter in django such that,

• if items are cba, abc, abd etc.. and
• if I want to get 开发者_StackOverflow中文版the items that contains ab,

the list should be ordered as abc,bca because abc starts with ab even though they both contains ab.

How can I make such query in django effectively ?

My query is at below

EmployerIndexed.objects.filter(name__icontains=empkw)

If I understand what you're asking, you want an alphabetical sort?

EmployerIndexed.objects.filter(name__icontains=empkw).order_by('name')
