Searching for a word or phrase inside a very big pdf consisting of thousands of pages will often freeze/not responding or take extremely long to return results. Can a feature be added where you can select a certain amount of pages to be isolated for the search and/or select a bookmark or tree branch to be isolated for a search thereby only indexing a section of the pdf for your search term.

This is a headache my whole team at my company consisting of over a thousand employees are facing on a daily basis.
