Description

Here's the use-case I am trying to solve for document level access control.

Documents :

[
  {"id" : "1", "users" : ["user1"]},
  {"id" : "2", "users" : ["user4"]},
  {"id" : "3", "users" : ["user1", "user2"]},
  {"id" : "4", "users" : ["user1", "user2", "user3"]},
  {"id" : "5", "users" : ["user1", "user2", "user3", "user4"]}
]

 

Query : If the document has any user apart from user1, user2 or user3 don't show it.
Results : id:1, id:3, id:4

Query : If the document has any user apart from user1, user2 don't show it.
Results : id:1, id:3

I'm thinking this can be solved by writing a post-filter

Syntax:

{!union_has_all field=users}user1,user2,user3

The post filter would get each document at a time and see if there is a user in that document that is not part of the query.
