How to create filter by value of unrelated model?

[SuperMasterBlasterLaser]

Hello.

First of all, I want to thank all contributors for this lib. I have some case in my project.

Lets say that I have these models:

class Company(model.Model):
    identifier = model.CharField(unique=True, max_length=25)

class Item(model.Model):
     supplier_identifier = model.CharField(max_length=25)

The models Company and Item are not related by any foreign key. Lets just say that I have reasons for that. I want to filter Item models by its supplier_identifier field and autocomplete values should be provided from Company model's identifier field.

I know that I should prepare special View for searching. However I don't know how to force filter to get value of specific field.
