The Firebase documentation states the following for the not-in operator:
to combine up to 10 not equal
!=clauses on the same field with a logicalAND. Anot-inquery returns documents where the given field exists, is notnull, and does not match any of the comparison values.
I am assuming this not-in operator cannot be used on a field on a document that is an array, correct? As in if I had an array field containing userID's on a document, I can't use the not-in`` operator to query docs where a particular userID is not in that array field.
