The Solr schema.xml has by default the “string” fieldType.

<fieldType name="string" class="solr.StrField" sortMissingLast="true" />

Add the following fieldType to your schema.xml and use it as field type for your field:

<fieldType name="string_rev" class="solr.TextField" sortMissingLast="true">     <analyzer type="index">         <tokenizer class="solr.KeywordTokenizerFactory"/>         <filter class="solr.LowerCaseFilterFactory" />         <filter class="solr.PatternReplaceFilterFactory" pattern="(\s+)" replacement="" replace="all" />         <filter class="solr.ReversedWildcardFilterFactory" />
