Is it possible to compile a latex-document in such a way, that you can search for math formulas in the resulting pdf file by searching for the corresponding latex code? For example open the resulting document in evince and search for \int_3^5 f and you will find all occurrences the typeset math formula where the source contained \int_3^5 f.

The normal pdf search function should be unaffected.

I think in principle this should be possible since you could parse the math information at compile time and add them appropriately to the pdf ocr layer. However is there already a package or option which implements this?

  • As a simple workaround: You could print the code invisible (white color on white background using verbatim) and use negative spaces to align stuff right. – Skillmon Mar 16 '17 at 08:38

    I think the accsup package is what you're looking for: http://tex.stackexchange.com/questions/119713/making-equations-copyable-in-pdf – JPi Mar 16 '17 at 08:57
