Wildcard queries are not analyzed, so you are getting what you type -
which doesnt match what went through an analyzer and into the index. I
don't think Solr has a solution for this at the moment. I think Lucene
has a special analyzer with deals with this to some degree, but I have
never used it.

Hi all,
could somebody help me to understand why I can not search with wildcard if I
use the solr.ASCIIFoldingFilterFactory?
So I get results if I am searching for "münchen", "munchen" or "munchen*",
but I get no results if I do the search for "münchen*". The original records
contain the terms "München" and "Münchener".
The solr.ASCIIFoldingFilterFactory is configured on both sides index and
query. We are using the 1.4-dev version from trunk.
<fieldType name="text" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<filter class="solr.ASCIIFoldingFilterFactory"/>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<filter class="solr.ASCIIFoldingFilterFactory"/>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Thank you very much!
Regards,
Vladimir
