[Zope] ZCatalog: searching for parts of words?

Hello Zopestas, is there a way to use the full textindex of ZCatalog for finding parts of words? For Example: seeking for 'word' would also bring up 'words'? I'm not sure, whether this is just a special issue in German - due to the fact that German accepts any thinkable and unthinkable combination of joined nouns. regards thomas -- fon: ++49 (0)40 42878 3781 fax: ++49 (0)40 42878 2728
