[Chicago-talk] Regular expression discussion.

[Warren Lindsey]

Hi Rich,

A soundex search is commonly used to match words that could be
misspelled. However, it targets more phonetic spelling errors instead
of OCR errors.

Google 'perl regex fuzzy search' and check out these two modules:

String::Approx
Regex::Approx

Cheers,
Warren

I have a perl script that at the moment just uses grep to look though text files that have been converted from pdf2text to see what sort of documents they are.  What I am finding however is that a lot of searches fail by just a few characters.
