Boolean search expressions -> regex converters?

[Paul Makepeace]

Is anyone aware of modules that'll convert "advanced" boolean expressions to
regexes? E.g. stuff like

Perl same (module* or package*) or ((boolean n/6 regex) same  (parser* or
convert*))

(Perl in the same para as module\S* or package\S*, or boolean within six
words of regex, same para as parser* or convert*)

I was going to paste in a copy of Factiva's login-authorized expression help
page<http://customer.factiva.com/en/custSvc/CSMain.aspx?&id=3463&sa_from=GL&rty=1&APC=&>but
it's HTML-formatted and couldn't immediately find a rich text
pastebin...
