Here's a simple site search for DW2004 css-p search boxes

If you need a simple site search cgi script for the search box on
css-p pages in Dreamweaver 2004, look at:
http://tesol.net/scripts/SillySearch/ It is FREE and does a quick
job searching specific directories (or all) on your own site. The
output of the search results is a clear and concise list.

You will need to cut, and paste the input form code to your own css-p
page to retain your "look and feel", unless you want to use the canned
search box that comes with the program. You can test the working demo
at tesol.net.
