Nick, I was assuming that when we do queries framework will check
WHERE condition and make request to datastore using index with
properties alphabetically sorted.
So if I query
Foo.all().filter("col1", 1).filter("col2", 2)
or
Foo.all().filter("col2", 1).filter("col1", 2)
it will use the same index:
-kind: Foo
properties:
- name: col1
- name: col2
Isn't it the case?
