"CoSt" was split into two terms and the query parser generated an OR of
them. Adding the autoGeneratePhraseQueries="true" attribute to your field
type should fix the problem.
You can also change splitOnCaseChange="1" to splitOnCaseChange="0" to avoid
the term splitting issue.
Be sure to completely reindex in either case.

Subject: search behavior on a case-sensitive field
I have a search like this:
<fieldType name="text_cs" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory"
ignoreCase="true" words="stopwords.txt"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1"
catenateWords="1" catenateNumbers="1" catenateAll="0"
splitOnCaseChange="1"/>
<!-- <filter class="solr.LowerCaseFilterFactory"/> -->
<filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
When I query "COST", it gives reasonable results (n1);
When I query "CoSt", however, it gives me n2 (>n1) results, and I can't
locate actual occurence of "CoSt" in the docs at all. Can anybody advise?
