I just added a search feature to the site. I looked at several third-party solutions and settled on Atomz.com. Google offers this service, but it only searches their archive of your site, which could be weeks old. Atomz lets me schedule a weekly indexing and request a fresh one whenever I want. They also provide a list of which search terms are used.

On my home page at the bottom I added a simple search box which will return all the pages which contain all your search words. If that's not powerful enough, I've also added an advanced search page which lets you do all sorts of cool stuff, such as sound-alike spelling (for you bad spelerz out there) and searches by date or finding matches on any of several words you specify.

I've also started adding the simple search box plus a link to the advanced one on my other pages, usually at the top right of the page.

I will be interested in seeing what words people search for on this site.
