Jan Høydahl commented on SOLR-219:
----------------------------------
Agree with Gunnar that the problem is wider than lowercasing. How hard would it
be to let each filter choose whether to work on prefix terms or not, and run
them through analysis?
A use case is for the Nordic characters æøåäö. A Norwegian name "Øyvind" would
typically be normalized and indexed as "oeyvind", and when a swede searches for
"Öyvin*", he'd get match if at least the mappingCharFilter and LowercaseFilter
were allowed to run and turn the query into "oeyvin*".
