GAE model properties can be removed from built-in index by setting "indexed" to false.
In DjangoAppEngine, I don't see an API to set model fields to not be indexed. How do I set a model field as such?

1See use of 'unindexed' here: http://djangoappengine.readthedocs.org/en/latest/db.html#indexes – mechanical_meat Apr 30 '14 at 14:47

Perfect, thanks Bernie! If you add your comment as an answer, I'll mark it as the answer. – jacob Apr 30 '14 at 17:07

Per the excellent documentation you would use 'unindexed' as explained here:
http://djangoappengine.readthedocs.org/en/latest/db.html#indexes
In case you prefer not to follow the link here's a code-sample:
from myapp.models import MyContact
FIELD_INDEXES = {
MyContact: {
'indexed': [...],
'unindexed': ['creation_date', 'last_modified', ...],
},
}

Actually I have one other question, in case you know: If a field is marked unindexed, can it still be included in a composite index? – jacob Apr 30 '14 at 17:15

I don't know. I kinda doubt it. You should test that assumption of mine out though. – mechanical_meat Apr 30 '14 at 17:23

Ok, I found out that unindexed property can not be in a composite index. More here: https://code.google.com/p/googleappengine/issues/detail?id=4231 – jacob Apr 30 '14 at 17:33
