Search a pdf

Use case or problem

When I have an open PDF, Command-F should allow me to find things as it does in md files, so that I can quickly go to the key point I am looking for.

Proposed solution

Add a rudimentary search feature for inside the PDF. Does not need to do OCR, just a basic effort. (Many are off by a bit for some reason).

Current workaround (optional)

This is different from Search text in PDFs - I want to be able to search the PDF when it’s open, mainly for navigation. 511 wants to do full text search from within the vault.
