[Mediawiki-l] Problems with search

[Günter Gratzer]

hello,
if I use search function in our mediawiki I often didn't get a result.
e.g. if I search for "vpn" I don't get a result. If I enter "vpn-verbindung" the page is found. If I enter "verbindung" the page will be found as well.
 
Anyone can explain me why it doesn't work?
 
We use

*	MediaWiki <http://www.mediawiki.org/> : 1.11.0 
*	PHP <http://www.php.net/> : 5.2.1 
*	MySQL <http://www.mysql.com/> : 5.0.37

thanks!

Günter
