xwiki case sensitive search

Hi, I am working on XWiki. Presently the search tool for searching in attachment contents is case sensitive .If I want to make it case insensitive, what changes I have to make in its code. Here is the code for attachment content search in xwiki. Search in attachment file content #set($sql= ", XWikiAttachment attach, XWikiAttachmentContent as attachc where doc.id = attach.docId and attach.id = attachc.id and attachc.content like '%$text%' ") #foreach ( $item in $xwiki.searchDocuments($sql , $nb , $start)) #if ($xwiki.hasAccessLevel("view", $context.user, "${context.database}:${item}")) #set($bentrydoc = $xwiki.getDocument($item)) * [$bentrydoc.name>${bentrydoc.web}.$bentrydoc.name] by $xwiki.getLocalUserName($bentrydoc.author) on $xwiki.formatDate($bentrydoc.date, $formatDate) #end #end Thanks, Anuj
