Hi Christian,
Please use the following filter before/above the stemmer.
<filter class="solr.KeywordRepeatFilterFactory"/>
Plus, you may want to add :
<analyzer type="multiterm">
<tokenizer class="solr.KeywordTokenizerFactory" />
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.GermanNormalizationFilterFactory"/></analyzer>

Hi Ahmet,
Many thanks for your reply. I had a look at the URL you pointed out but,
honestly, I have to admit that I did not fully understand you.
Let's be a bit more concrete. Following the schema snippet for the
corresponding field:
...
<field name="title" type="text_de" indexed="true" stored="true"
required="false" multiValued="false" />
<!-- German -->
<fieldType name="text_de" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="lang/stopwords_de.txt" format="snowball" />
<filter class="solr.GermanNormalizationFilterFactory"/>
<filter class="solr.GermanLightStemFilterFactory"/>
<!-- less aggressive: <filter
class="solr.GermanMinimalStemFilterFactory"/> -->
<!-- more aggressive: <filter class="solr.SnowballPorterFilterFactory"
language="German2"/> -->
</analyzer>
</fieldType>
...
What is wrong with this schema? Respectively, what should I change to be able
to correctly do wildcard searches?
Many thanks for your time. Cheers,
christian

Subject: Re: Wildcard search not working
Hi Chiristian,
The query r?che may not return at least the same number of matches as roche
depending on your analysis chain.
The difference is roche is analyzed but r?che don't. Wildcard queries are
executed on the indexed/analyzed terms.
For example, if roche is indexed/analyzed as roch, the query r?che won't match
it.
Please see : https://wiki.apache.org/solr/MultitermQueryAnalysis

Hi,
What would be the reasons making the wildcard search for Lucene Query Parser
NOT working?
We are using Solr 5.4.1 and, using the admin console, I am triggering for
instance searches with term 'roche' in a specific core. Everything fine, I am
getting for instance two matches. I would expect at least the same number of
matches with term 'r?che'. However, this does NOT happen. I am getting zero
matches. Same problem occurs with 'r*che'. 'roch?' does not work neither but
'roch*' works.
Switching debug mode brings following output:
"debug": {
"rawquerystring": "roch?",
"querystring": "roch?",
"parsedquery": "text:roch?",
"parsedquery_toString": "text:roch?",
"explain": {},
"QParser": "LuceneQParser",
...
Any idea? Thanks and cheers,
christian
