George - wildcard expressions, in Lucene/Solr's QueryParser, are not
analyzed. There is one trick in the API that isn't yet wired to
Solr's configuration, and that is setLowercaseExpandedTerms(true).
This would solve the Sol* issue because when indexed all terms for the
"text" field are lowercased during analysis.
An functional alternative, of course, is to have the client lowercase
the query expression before requesting to Solr (careful, though -
consider AND/OR/NOT).

Hi Folks,
Can someone tell me what I might have setup wrong? After indexing
my data,
I can search just fine on, let say "sol*" but not on "Sol*" (note
upper case
'S' vs. lower case 's') I get 0 hits.
Here is my customize schema.xml setting:
<fieldType name="text" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/> -->
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="0" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
<analyzer type="query">

<!-- <filter class="solr.SynonymFilterFactory"

generateWordParts="0" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
Btw, "Solr", "solr", "sOlr", etc. works. It's a problem with wild
cards.
Thanks in advance.
