Summary: Union Has All Post Filter Query
Key: SOLR-12673
URL: https://issues.apache.org/jira/browse/SOLR-12673
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Varun Thacker
Here's the use-case I am trying to solve for document level access control.
Documents :
{code:java}
[
{"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"]}
]{code}
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:
{code:java}
{!union_has_all field=users}user1,user2,user3{code}
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.
