Oops forgot you wanted the ProductID's as well, this will work but may return some results with the product ID if some products descriptions contain the product ID number, again this could be a seperate substring variable like $substring_id that could easily be added to the search form as an additional "Search for Product ID" field.

	if ($store_language != $config["default_customer_language"] && $substring) {
	
		$substring_query = "AND (($sql_tbl[products].product like '%$substring%' or $sql_tbl[products].descr like '%$substring%' or $sql_tbl[products].fulldescr like '%$substring%' OR $sql_tbl[products].productcode like '%$substring%' OR $sql_tbl[products].productid like '%$substring%') OR ($sql_tbl[products_lng].code='$store_language' AND ($sql_tbl[products_lng].product LIKE '%$substring%' OR $sql_tbl[products_lng].descr LIKE '%$substring%' OR $sql_tbl[products_lng].full_descr LIKE '%$substring%' OR $sql_tbl[products].productcode like '%$substring%' OR $sql_tbl[products].productid like '%$substring%')))";

		$search_query_count = "select count(*) from $sql_tbl[pricing], $sql_tbl[categories], $sql_tbl[products] LEFT JOIN $sql_tbl[products_lng] ON $sql_tbl[products].productid=$sql_tbl[products_lng].productid where $sql_tbl[pricing].productid=$sql_tbl[products].productid and $sql_tbl[pricing].quantity=1 and $sql_tbl[products].categoryid=$sql_tbl[categories].categoryid $membership_condition and ($sql_tbl[pricing].membership='". $user_account['membership']."' or $sql_tbl[pricing].membership='') AND $category_condition and $sql_tbl[products].forsale='Y' and $sql_tbl[categories].avail='Y' $price_condition $substring_query group by $sql_tbl[products].productid";

	}
	else {
		$substring_query = "AND ($sql_tbl[products].product like '%$substring%' OR $sql_tbl[products].descr like '%$substring%' OR $sql_tbl[products].fulldescr like '%$substring%' OR $sql_tbl[products].productcode like '%$substring%' OR $sql_tbl[products].productid like '%$substring%')";

		$search_query_count = "select count(*) from $sql_tbl[products], $sql_tbl[pricing], $sql_tbl[categories] where $sql_tbl[pricing].productid=$sql_tbl[products].productid and $sql_tbl[pricing].quantity=1 and $sql_tbl[products].categoryid=$sql_tbl[categories].categoryid $membership_condition and ($sql_tbl[pricing].membership='". $user_account['membership']."' or $sql_tbl[pricing].membership='') and ($sql_tbl[products].product like '%$substring%' or $sql_tbl[products].descr like '%$substring%' OR $sql_tbl[products].productcode like '%$substring%' OR $sql_tbl[products].productid like '%$substring%') AND $category_condition and $sql_tbl[products].forsale='Y' and $sql_tbl[categories].avail='Y' $price_condition $substring_query group by $sql_tbl[products].productid";

Same lines of code in 3.4.5 (81 to 92).
