<field name="content" type="text_general" indexed="true" stored="true" multivalued="false" />  <fieldtype name="text_general" class="solr.textfield" positionincrementgap="100" multivalued="true">   <analyzer type="index">     <tokenizer class="solr.whitespacetokenizerfactory"/>     <filter class="solr.stopfilterfactory" ignorecase="true" words="stopwords.txt" />     <!-- in example, use synonyms @ query time     <filter class="solr.synonymfilterfactory" synonyms="index_synonyms.txt" ignorecase="true" expand="false"/>     -->     <filter class="solr.lowercasefilterfactory"/>   </analyzer>   <analyzer type="query">     <tokenizer class="solr.whitespacetokenizerfactory"/>     <filter class="solr.stopfilterfactory" ignorecase="true" words="stopwords.txt" />     <filter class="solr.synonymfilterfactory" synonyms="synonyms.txt" ignorecase="true" expand="true"/>     <filter class="solr.lowercasefilterfactory"/>   </analyzer> </fieldtype>
