Hi

I'm tring to mofidy search engine to add other fields

I have "Product" page with fields: 'content' and 'technical information'

first i added Product to classesToSearch in SearchForm action

    function SearchForm() {

        $searchText = isset($this->Query) ? $this->Query : 'Znajdź produkt';
        $fields = new FieldSet(
                        new TextField("Search", "", $searchText)
        );
        $actions = new FieldSet(
                        new FormAction('results', 'szukaj')
        );

        $form = new SearchForm($this, "SearchForm", $fields, $actions);
        $form->classesToSearch(array('SiteTree', 'Product'));

        return $form;
    }

next modified SearchForm.php like that:

	/**
	 * Classes to search
	 */	
	protected $classesToSearch = array("SiteTree", "Product", "File");


       function classesToSearch($classes) {
            $illegalClasses = array_diff($classes, array('SiteTree', 'Product', 'File'));
            ..
            $legalClasses = array_intersect($classes, array('SiteTree', 'Product', 'File'));


       public function searchEngine(..............) {
          $extraFilters = array('SiteTree' => '',  'Product'=>'', 'File' => '');
          
          .....

          if($keywords) {
              $match['Product'] = "MATCH (Content, TechnicalInformation) AGAINST ('$keywords') AND ClassName = 'Product'";
              $relevance['Product'] = "MATCH (Content, TechnicalInformation) AGAINST ('$relevanceKeywords' IN BOOLEAN MODE)";
          }


 	  // Generate initial queries and base table names
	  $baseClasses = array('SiteTree' => '', 'Product'=>'', 'File' => '');

          foreach($this->classesToSearch as $class) {
              ...
              $baseClasses['Product'] = '`Product_live`';
          }

 	  // Make column selection lists
 	  $select = array(
             'Product' => array("ClassName", "$baseClasses[Product].ID","_utf8'' AS ParentID","Content","TechnicalInformation", "$relevance[Product] AS Relevance", "NULL AS CanViewType"),
          )


          foreach($queries as $query) {
		$querySQLs[] = $query->sql();
		//$totalCount += $query->unlimitedRowCount();                 (comented)
          } 

       }
}

and i don't know why but i get error

[User Error] Couldn't run query: SELECT ClassName, `Product_live`.ID, _utf8'' AS ParentID, Content,TechnicalInformation, MATCH (Content,TechnicalInformation) AGAINST ('something' IN BOOLEAN MODE) AS Relevance, NULL AS CanViewType FROM `Product_live` WHERE (MATCH (Content,TechnicalInformation) AGAINST ('something*') AND ClassName = 'Product') AND (`SiteTree_Live`.ClassName IN ('Product')) ORDER BY Relevance DESC LIMIT 0, 10 Unknown column 'SiteTree_Live.ClassName' in 'where clause'

what is this 'AND (`SiteTree_Live`.ClassName IN ('Product'))' and how to fix it ?
