As a developer it’s currently too difficult or in some cases impossible, to filter assets correctly using the AES. CatalogSearchParams lacks a “CreatorType” filter (though one of the many documentation pages claims it has it, it does not). If a user and a group share a name, letter for letter, the AES only returns user uploads and makes no attempt to return Group uploads.
I had to utilize the web API for catalog to finish a project for a friend, I shouldn’t have to do that when :SearchCatalog() exists.
CatalogSearchParams and AES should have more filters to make using proxies for Catalog API obsolete.
