Good idea.. maybe something like this :)
Properties that Aren't Indexed
Property values that aren't indexed are not findable by queries. This
includes properties that are marked as not indexed, as well as properties
with values of the long text value type (Text) or the long binary value type
(Blob).
To declare that a property be stored as non-indexed using the Model class,
provide the indexed argument to the property model constructor with the
value False, as follows:
class MyModel(db.Model):
unindexed_string = db.StringProperty(indexed=False)
A query with a filter or sort order on a property will never match an entity
whose value for the property is a Text or Blob, or which was written with
that property marked as not indexed. Properties with such values behave as
if the property is not set with regard to query filters and sort orders.
