Improved search filtering

A few ideas to improve search results:

Prioritize (or allow to prioritize) results to core content. I'm often looking for a rule and the first several results are from adventure modules that I may or may not own (Rick & Morty, for example). It can be difficult as a DM, especially in the middle of a game, to try to reference a rule quickly while having to scroll through content I don't need.
Add a search feature for the book that I'm currently in, rather than site-wide. If I know that certain information is in the DMG, for example, I'll often have that book already open. It'd be great to only get results from that book (without having to open up advanced filters)
Have the option to automatically exclude searches in content I don't own. This sounds like it might be complicated on the backend, but I'm confident in your team's abilities!
