[Feature request] add advanced search to the Reader

[Noexpert]

Would it be possible to add advanced search functionality to the Reader?

Specifically, it would be useful to have a window that displays the surrounding words around the search term.
Acrobat has this (see screenshot, below) and it's helpful, as it displays the context around each search result.

This way, the user can quickly scroll through the results and focus on the one they want.
Otherwise, the user has to sequentially go through all the search results, which can be time consuming for large documents.

If you want to test it, use ctrl + shift + F in Acrobat.
