This is fairly easy. Take a look at the examples in the cgi-bin directory,
especially the "cal" command. Copy it to a file like "keysearch" and modify
it in such a way that it does a "grep" on the listing file and returns
the result embedded in <PRE> </PRE>.
Now you can do keyword searches by accessing "/htbin/keysearch".
You can also create a forms interface which makes it easier for users to
use your keyword searching mechanism.

For more complicated search tasks, I recommend our public domain ICE
search extension package. I will soon release a new version which is
CGI compliant (sorry Rob and Ari.. you were right. It needs to have
a cgi-bin interface, not a server hack).

Contact me by email if you need further help - but please wait until next
week, since I am extremely busy preparing for the german CeBit computer fair.
