Pier Search Component

[Lukas Renggli]

I published a new snapshot of pier (http://mc.lukas-renggli.ch/pier)  
that replaces the query engine with a simple full-text search. If you  
have Scriptaculous loaded it even updates life while you type the  
expression, that demoes its speed.

Have fun,
Lukas
