it is working for q=chrétien and find documents with "chretien" but
searching for q=chré* does not work, but q=chre* works fine.
is this a bug or I am doing something wrong?
It's a bit tricky here.... Lucene's QueryParser, the heart of
Solr's query parsing, does not analyze wildcard query parts.
Consider stemmed words, for example, on why that is a problem. In
this case it does make sense to run it through a filter that
normalizes diacritics on characters, but unfortunately Solr doesn't
support what you need at this point.
Further on this, QueryParser does have some settings specific to
wildcard queries, such as lowercasing the prefix part.
Perhaps this is a case that Solr could address with a third analyzer
configuration (it already has "query", and "index" differentiation)
that could be incorporated for wildcard queries. Thoughts on that?
