+- [ ] When parseFilter, get list of UUID as value for relationship
+- [ ] Add new operation in Filter evalue: IN and !IN
+- [ ] parseNewData can use filter like in "Add User (friends = [10] {age > 20})" to return UUID
+- [ ] parseFilter can use sub filter. "GRAB User {friends IN {age > 20}}" At least one friend in a list of UUID
