I am hoping to install a search engine to my website, www.creaturefeature.info. Does anyone have any suggestions or methods I could use?

http://www.google.com/searchcode.html

Look at the third one down the page

In case what Jim says is not what you're talking about, try out http://www.xav.com/scripts/search/ This is if you meant a method for people to search your site for something. Google, while good, doesn't always index everything.

Zoom is quite nice too. Free for small sites.

Thanks, guys. I think I'll be installing xav.com's search engine.
