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?
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', ...],
},
}
