Multiple filter rules for one index

I’m trying to set up several filtering rules for the same index, but only the first one works. Here is an example configuration

- name: First_rule
    proxy_auth:
      users: ["*"]
    ldap_authorization:
      name: "ldap1"
      groups: ["ldap_group1"]
    indices: [ "index1-*", "index2-*"]
    actions: ["indices:data/read/*"]
    filter: '{"prefix": {"description": {"value": "description1"} } }'

 - name: Second_rule
    proxy_auth:
      users: ["*"]
    ldap_authorization:
      name: "ldap1"
      groups: ["ldap_group1"]
    indices: [ "index1-*", "index2-*"]
    actions: ["indices:data/read/*"]
    filter: '{"prefix": {"description": {"value": "desсription2"} } }'

When I search by index pattern index1-* in Kibana Discover tab, I get only documents with a field equal to description=description1
Is it possible for these two rules to apply?

The filter rule accepts boolean queries, so you can use the Elasticsearch DSL to create a boolean query with two conditions in logic OR.
