One thing to note is that query "au:Schröder, Jürgen" is being  
translated (try &debugQuery=true to see) to:

	au:schröder  <AND/OR> <defaultField>:jürgen

AND/OR depends on how you have things configured, as well as the  
default field.

You probably want to use the ISOLatin1AccentFilterFactory to have the  
diacritics "flattened" to the ASCII character they look like.
