See the search filtering documentation for details about the query syntax. The searchable attributes and the operators each one accepts are listed in the request body below.

User-specific notes

• contact takes a contact search filter with any, not a plain reference:
  { "contact": { "any": { "contact": { "equal": "/v1/contacts/1000" } } } }
{ "contact": { "any": { "last_name": { "equal": "Smith" } } } }
• login is the email address the user signs in with:
  { "login": { "ends_with": "@example.com" } }
• user_id matches users by numeric ID, e.g. { "user_id": { "any": [1000, 3000] } }.
