? PDF works fine for searching.
It depends on the document, a pdf page could be:
1) Text
2) An image of text
3) Lines/Curves that happen to be in the shape of letters/text
If it's text it perfectly searchable. If it's one of the others the creator has to also OCR it and add the text behind the image or in front but invisible (no stroke or fill).

- jfk13 7y agoIf you set the \XeTeXgenerateactualtext=1 option in a Xe(La)TeX document, the resulting PDF will include ActualText annotations to support searching even in complex scripts with ligatures, character reordering, etc.
