php - Case insensitive search in Apache solr -


i created search application type string in solr php , working fine. issue found can not support case insensitive search. upon searching found solr doesn't support case insensitive search type "string".

so created custom type "string_ci" , configured below.

    <field name="id" type="string" indexed="true" stored="true" required="true" multivalued="false" /> -     <field name="loc_code" type="string" indexed="true" stored="true" required="true" multivalued="false" />     <field name="loc_name" type="string_ci" indexed="true" stored="true" required="true" multivalued="false" />     <field name="state" type="string" indexed="true" stored="true" required="true" multivalued="false" />

this field type definition "string_ci"

    <fieldtype name="string_ci" class="solr.textfield"             sortmissinglast="true" omitnorms="true">             <analyzer>                 <tokenizer class="solr.keywordtokenizerfactory"/>                            <filter class="solr.lowercasefilterfactory" />        </analyzer>     </fieldtype>

unfortunately, not working. can point out went wrong ?

try 

<fieldtype name="string_ci" class="solr.textfield" sortmissinglast="true"    omitnorms="true" positionincrementgap="100">   <analyzer type="index">     <tokenizer class="solr.keywordtokenizerfactory"/>       <filter class="solr.lowercasefilterfactory"/>   </analyzer>   <analyzer type="query">     <tokenizer class="solr.keywordtokenizerfactory"/>     <filter class="solr.lowercasefilterfactory"/>   </analyzer> </fieldtype>
