Would it be possible that searches recover not just the entry with the match, but the exact position (e.g., text highlighted) of the match? I am thinking about both the abstract of a journal article and, more interestingly, the associated pdf of the whole article/book.

I understand that, with pdfs, Zotero stores the index, but the vieweing, etc, of the file is dispatched to an external editor so maybe this just cannot be done.
