Exact match

Hi,
 
I am doing exact search in Solr .In Solr admin page I  am giving the search input string for search.
For ex: I am giving “channeL12” as search input string in solr home page it displays search results as 
 
<doc>
  <str name="url">http://rediff</field>
  <str name="title">first</field>
  <str name="description">channeL12</field>
</doc>
 
As there is a matching input for “channeL12”.
 
If I give “channel12” as search input string with L in lower case I am not getting any search results.
 
In fact I changed ignoreCase =”true” in schema.xml
 
schema.xml
<analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory" ignoreCase="true" />
</analyzer>
 
I want to ignore casesensitive search in my search results.
 
Please let me know if I need to make changes any where else or what to do to achieve the desired output.
 
Regards
Bhaskar

First of all, WhitespaceTokenizerFactory does not have an ignoreCase parameter. You need to add 
<filter class="solr.LowerCaseFilterFactory"/>
to your both query and index analyzer.

<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>

But i think it will be more convenient for you to use the same analyzer for index and query.

Hope this helps.
