The bug is repetable and seems to be integrated in LSDB since the beginning
If you type in the searchengine or in artist "Sven V" = Sven Väth, ...Sven Van Hess.. Sven Vath appears
If you type in the searchengine or in artist "Sven Vä" = Sven Vath appears (as the "ä" is nether part of the language of the netherlands nor english, the programmer might have missed to make a connection within the database when you type an "ä")
Conclusion : Type in "Sven V" and KLICK on "Sven Väth"
