Currently Primal's cache service is using a custom cache filter to serve requests that cannot be fulfilled with regular Nostr filters.
See nostrability/nostrability#168 (comment) for an alternate approach, based on NIP-50 search extensions. Basically you just cram everything into the search field. This has been working well for me, and I think most of Primal's requests could be served this way too.
