 Public String searchStr{get;set;}
   Public TestSOSLController(){

  Public void soslDemo_method(){
   accList = New List<account>();
   if(searchStr.length() > 1){
   String searchStr1 = '*'+searchStr+'*';   
   String searchQuery = 'FIND \'' + searchStr1 + '\' IN ALL FIELDS RETURNING  Account (Id,Name,Type,Rating,Phone)';
   List<List <sObject>> searchList = search.query(searchQuery);
   accList = ((List<Account>)searchList[0]);
   
   if(accList.size() == 0){
       apexPages.addmessage(new apexpages.message(apexpages.severity.Error, 'Sorry, no results returned with matching string..'));
