Here's the URL that you get by clicking the title of HowToWiki:
http://www.eichemiller.com/cgi-bin/lexicon?search=HowToWiki
Looking at the search URL may suggest that you can search for other things, not just page titles.
You can! Like "Character" and "Dwimmerlaik".
http://www.eichemiller.com/cgi-bin/lexicon?search=Character
http://www.eichemiller.com/cgi-bin/lexicon?search=Dwimmerlaik
But there isn't a search form yet. To search, copy in the search prefix to your browser and add the text you're searching for.
