Solr Use UUID

1. schema.xml修改：
   
   • <fieldtype class="solr.UUIDField" indexed="true" name="uuid"></fieldtype>
   • <field name="id" type="uuid" indexed="true" stored="true" default="NEW"/>
     
2. solrconfig.xml修改：
   註解掉
   <searchComponent name="elevator" class="solr.QueryElevationComponent" >
       <str name="queryFieldType">string</str>
       <str name="config-file">elevate.xml</str>
     </searchComponent>
   <requestHandler name="/elevate" class="solr.SearchHandler" startup="lazy">
       <lst name="defaults">
         <str name="echoParams">explicit</str>
       </lst>
       <arr name="last-components">
         <str>elevator</str>
       </arr>
   </requestHandler>
