How to find document in CouchDB where document has an array that contains a specific string?

I am just getting started working with CouchDB.

We have a database where the documents look like:

  "_id": "43538c8409dd",
  "_rev": "123",
  "audit": false,
  "members": {
    "users": [
      {
        "dn": "cn=newuser1,ou=people,dc=foo,dc=com",
        "dateAdded": "2020-12-02T16:52:41:748Z"
      },
      {
        "dn": "cn=newuser2,ou=people,dc=foo,dc=com",
        "dateAdded": "2020-12-02T16:52:41:748Z"
      }
    ],
    "groups": []
  },
.
.
.
}

I am trying to find all documents in the database that contain (for example) "dn" with value "cn=newuser1,ou=people,dc=foo,dc=com".

I have tried a selector like:

   "selector": {
      "users": {
         "$elemMatch": {
            "dn": "cn=newuser1,ou=people,dc=foo,dc=com"
         }
      }
   }
}

I know that there are several documents that should match, but I am getting "No Documents Found".

Can someone tell me why this search is not working?

Thanks, Jim

Solution

The rather important members field is not being specified. This is likely the query intended

{
   "selector": {
      "members.users": {
         "$elemMatch": {
            "dn": "cn=newuser1,ou=people,dc=foo,dc=com"
         }
      }
   }
}
