I also would like this feature. Ideally, the feature would include searching through all PDFs. I agree with you that would be slow, and would almost certainly require maintaining an index. However, the option of searching through the text in a SINGLE file (presumably the one that is open) would be fast and much easier to implement and more useful, at least to me. One could make a strong use case for this implementation. For example, I have a volume of Sweelinck organ works that is 260 pages. I wanted to find the toccatas in it, so I exported it, OCR'd it, and found them. It would have been MUCH easier to open it in MobileSheets and search for "toccata". I do hope you will consider implementing this feature on a per-piece basis.
