GQL query with multiple condition on one List field

Question

I want to get object, which listfield contains 'foo', 'bar' and 'foobar' strings. Can I do query like this

SELECT * FROM Entity WHERE listfield = 'foo' AND listfield = 'bar' AND listfiled = 'foobar'

where listfield = StringListProperty() ?

Answer 1

One thing to note, make sure that your index.yaml file contains all the index permutations you require. Your query as above would have an index like this:

• kind: Entity properties:
  • name: xyz
  • name: listfield
  • name: listfield
  • name: listfield

Answer 2

Yes, you can do that.
