    } catch (Exception e) {
      ApexPages.addMessages(e);
    }

  }

  // runs the search with parameters passed via Javascript
  public PageReference runSearch() {
try{
FAQ__c f=new FAQ__c();
    String question = Apexpages.currentPage().getParameters().get('Question__c');
    String answer = Apexpages.currentPage().getParameters().get('Answer__c');
   
  
    
    soql = 'select Question__c, Answer__c from FAQ__c where Question__c!= null';
     if (!question.equals(''))
      soql += ' and Question__c LIKE \'%'+String.escapeSingleQuotes(question)+'%\'';
    if (!answer.equals(''))
      soql += ' and Answer__c LIKE \'%'+String.escapeSingleQuotes(answer)+'%\'';
   // if (!accountName.equals(''))
     // soql += ' and account.name LIKE \''+String.escapeSingleQuotes(accountName)+'%\''; 
    
    // run the query again
    }
     catch(NullPointerException ne){
     ApexPages.addMessages(ne);
    }
    runQuery();

    return null;
    }
