Are Wildcard, Prefix, and Fuzzy queries case sensitive?
Unlike other types of Lucene queries, Wildcard, Prefix, and Fuzzy queries
are not passed through the Analyzer, which is the component that performs
operations such as stemming and lowercasing.
The reason for skipping the Analyzer is that if you were searching for
"dogs*" you would not want "dogs" first stemmed to "dog", since that would
then match "dog*", which is not the intended query.

: Ok, i corrected it.
:
: For a "normal" search without a "*" it works now. But when i do a
: search with an "*" or a "?" my newly implemented filter is not called and
for example my umlauts are not replaced by the analyzer(filter).
:
: I do a:
: Analyzer analyzer = new SpecialCharsAnalyzer();
: QueryParser parser = new QueryParser(DocumentFields.TEXT, analyzer);
: query = parser.parse(queryStr);
:
: For wildcards the tokenStream method of my analyzer isnt called.
: Whats my fault?
