Let say I have a product node with field categories as below

"categories": [
  "98a69699-0acd-4d8d-b743-9d9fb2b9830a", 
  "ae5dae88-488b-43ac-b857-b142d2fa3c33"
],

With url http://localhost:8080/magnoliaAuthor/.rest/delivery/products?categories=98a69699-0acd-4d8d-b743-9d9fb2b9830a&categories=ae5dae88-488b-43ac-b857-b142d2fa3c33 & [http://localhost:8080/magnoliaAuthor/.rest/delivery/products?categories[eq]=98a69699-0acd-4d8d-b743-9d9fb2b9830a&categories[eq]=ae5dae88-488b-43ac-b857-b142d2fa3c33], we could filter out products which contains at least these 2 categoryIds.

To achieve the "contains-any" operation, we try to negate the OR operation to AND-NOT-EQUAL operation with below url http://localhost:8080/magnoliaAuthor/.rest/delivery/products?categories[ne]=00000000-0000-0000-0000-000000000000, however, no products could be returned from such rest url. Seems a bit strange for the [eq] operator working on the uuid-list field while [ne] is not.

Would like to know if any chance there is an already-built function where we could achieve such use case. Please advise and thanks.
