I'm trying to mirror a large site where only about 30% of the content relates
to what I need. The directory structure doesn't present any opportunities to
segregate what I need from what I don't, but one certain phrase/string DOES
appear only in the content I want.

Is there a way to tell WinHTTRACK to crawl the provided URL in its entirety,
but only retrieve HTML pages containing a search string?
Thank you,
