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) (Free and Open Source)

  • And pdfgrep seems to have gained PCRE support in later versions, although sadly not the version in the ubuntu 14.04 repository. As it stands, it supports some subset of regex. – Eric Jan 24 '17 at 1:56

Our PDF viewer has regex searching (see http://www.jpedal.org/PDFblog/2012/03/search-pdf-files-with-regular-expressions-generating-teasers/)
