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

If you need a simple site search 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. See it at work in the demo.

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.
