Yes, there is a flag in QueryParser class called  
setAllowLeadingWindcard(boolean).
It is available since v2.1.

They probably would expect to find it.
But sometimes you find search options like "exact search phrase". Then  
it should find "schiff".
Else I would expect that the search engine adds wildcards in front and  
behind so that any words are found containing this token.

True. But when adding a leading wildcard for the user it will give the  
same result.
What about all the other languages?
Does this work in english actually?
