That phrasing may not have been overly helpful... but it's not a bad idea. The SO thread that poj mentioned in the similar Re: Longest common substring with N mismatches points out Bio::Grep::Backend::Agrep, whose synopsis reads to me like it probably does what the OP wants. The parent module Bio::Grep is what actually gets use'd, and lists some of the abilities of the various back-end modules, so the OP might want to check out that page as well for other pertinent information.
