Setting ramBufferSizeMB to a higher value seems to speed up the query
slightly. I have to continue with tuning though.

I am a little bit confused now. Doing a fuzzy search seems to work now
on a normal analyzed field. (Hmm, did I change something?) So the
analyzers are not breaking up such queries atm.

Also the prefix search does work (sometimes). I have started to test
this with a german umlaut "lehmhü*" to find "lehmhütte". This does not
work. But searching for "lehmhu*" does find the words. (I am using the
German2 snowball stemmer). Another problem is, that the prefix search
does not return highlight snippets. Is this an issue or did I forget a
configuration detail?
