Options to filter out non-channel pages from Search Queries result

Hi there,

Our implementation contains documents of certain type, some of which are mapped to channel pages via EssentialsDocumentComponent and some aren’t yet.

Currently, we are querying these documents using Delivery Tier Fluent Search API - Bloomreach Experience - Headless Digital Experience Platform which works fine. But, we need documents which are associated to channel pages and not others (as these ends up with /pagenotfound URL). Are there any options available to achieve this via Delivery Tier Fluent Search API ?

Thank you!
