Good Morning,
(I have searched for answer to my question, if I missed finding please point
me, thank you.)

I am trying to download only files ending in .html that contain a certain
string or strings, but have not quite figured it out.  I think I need the
/search/ filter but am unsure from there how to ensure I crawl the site and
download all files ending in .html containing the string(s), but no other
files.

Thank you in advance for any help or info.  Kind regards,
