i see. I'm reading through most of the documentation & comments on that issue - how would the tiger cache be able to support full-text searches on resources that a subject has access to? the API description in the issue post mentions

The Tiger Cache will expose one API, RoaringLookupResources, for returning the full set of accessible resources of the requested kind, for the requested permission, for a specific subject, in Roaring Bitmap form.

which (as far as i understand) is about listing the resources as opposed to performing some sort of searching on top of them?
