Hi everyone,

I’m building a client extension that uses `/o/search/v1.0/search` to fetch entries from a site scoped custom Object Definition across all scopes. Pagination and global keyword search work perfectly fine.

I am also able to filter and sort by standard system properties like `dateCreated`, `dateModified`, and `title` without any issues. However, I’m stuck when trying to filter or sort by the specific custom fields belonging to my Object Definition (for example, a `lastName` field). Whenever I attempt to pass a custom field name into the REST sort parameter, it returns an `InvalidSortException`.

My questions for the community:

1. Is there any supported syntax or workaround to sort or filter by a custom Object Definition field via `/o/search/v1.0/search`

2. Is there an alternative out-of-the-box headless endpoint (other than the site-scoped `/o/c/{objectname}/scopes/{siteId}`) that supports company-wide / cross-scope queries while allowing OData filtering and sorting on custom object fields?

Any pointers, documentation, or workarounds would be highly appreciated. Thanks!
