Is there software to allow me to search a PDF file with Regex?

I sometimes would like to search some particular words in a PDF file, however there are always a lot of unwanted words for me. For instance, when I would like to find "scala" in a PDF paper, I always come across "scalable", "scalability" or something like that. So I'm wondering whether there exists some reader that supports searching words with regular expressions.

PowerGrep does this. powergrep.com/pdf.html –  David Brabant Apr 24 '12 at 7:35
It appears that all you really want is to search for whole words. –  Dan D. Apr 24 '12 at 17:24

With regex search:

Without regex search:


  • grepWin, it supports regex, but doesn't support PDF files yet.


Without regex search:

  • pdfgrep (no GUI, available via apt-get)
