Documentation states:
'A query with a cursor does not always work as expected when the query
uses an inequality filter or a sort order on a property with multiple
values. Logic that de-duplicates the multivalued property for the
query does not persist
between queries, and may return a result more than once.'
Can I use query cursor on query that uses EQUALITY filter on a
property with multiple values ?
example
q = GqlQuery("SELECT * FROM A WHERE B = :1", something)
if not cursor_pos is None:
q.with_cursor(cursor_pos)
r = q.fetch(limit)
...
where A is defined like
class A(db.Model):
B = db.ListProperty(unicode)
C = db.StringProperty()
D = db.BooleanProperty()
...
I am trying something like that on my development server and it
doesn't work.
