[xwiki-users] Lucene and substring search

Hi, I have noticed that in the Lucene Search substrings are not found. E.g. The word 'Wallpapers' is on a page. When I search for 'wallpaper', 0 is found. The same when I search for 'wall'. When I search for 'wall*' or 'wallpaper*', the page is found. But this is not very inuitive for the user. The user would never think about using an asterisk. Can this behavior be changed? Thanks Reto
