I think you want to apply the LowerCaseFilterFactory:
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#head-2b63862c67c6c3a776b465bc8dec45db74ee05d2
Also, mess around with the /admin/analysis.jsp page to get a sense how
your fields getting tokenized.
This should work in 1.2 or 1.3

Hi,
I had tried by adding
<fieldtype name="nametext" class="solr.TextField">
<analyzer class="org.apache.lucene.analysis.WhitespaceAnalyzer"/>
</fieldtype>
<fieldtype name="text" class="solr.TextField">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StopFilterFactory"/>
<filter class="solr.PorterStemFilterFactory"/>
</analyzer>
</fieldtype>
in schema.xml.
But still problem is not resolved.
Also, already in my schema.xml the <filter
class="solr.LowerCaseFilterFactory"/> is already present.
My schema.xml is like this:-
<?xml version="1.0" encoding="UTF-8" ?>
