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.

Without regex search:

Other:

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

Linux
