For wildcard-queries the query parser is not running an analyzer and as the indexer
converts everything to lowercase you will not get any result if you have an uper-
case character in the wildcard-query.

Solr 1.5 will have some approaches to avoid this issue, but Solr 1.4 which is currently
used in eZ Find does not.
