This is something that I'd also be interested in. For the Google App Engine backend, you have the ability to create indexes that require more configuration than just on/off. But I don't think a single additional field would do the trick for my case.
Another option would be to open up the Meta class for custom attributes. There's a thread which discusses this here: https://groups.google.com/forum/#!topic/django-developers/JEDJYB41LGI The config might look something like this: class Article(db.models): class Meta: custom_indexes = {'field1': 'hash', 'field2': 'btree'} field1 = db.IntegerField() field2 = db.CharField() The tradeoff would be that the index would not be specified in the field description, but it would be close enough. (Currently for the app engine backend, you specify these in a separate file that the backend looks for.)
