Why does the search search by the ID of the IB element, but not by the name?

Question

1C-Bitrix

I can't figure out what the problem is. There are IB brands with a couple of dozen elements - when I enter the name of an element in the search (in my case, the brand) - 0 results, I drive in its ID - everything is shown ...
there are suspicions that something is wrong in the contents of the result_modifier.php file

<?
if($arResult["SEARCH"]){

$arID = array();
foreach($arResult["SEARCH"] as $i => $arItem)
{
if($arItem["MODULE_ID"] == "iblock" && substr($arItem["ITEM_ID"], 0, 1) != "S")
$arID[$arItem["ITEM_ID"]] = $i;
}
if (!empty($arID) && CModule::IncludeModule('iblock'))
{
  $grab = CIBlockElement::GetList(array('ID'=>'ASC'),array("ID" =>array_keys($arID)),false,false,array("ID","IBLOCK_ID","PREVIEW_PICTURE","CATALOG_GROUP_1"));
  while($ar = $grab->Fetch()){
  $arResult["SEARCH"][$arID[$ar["ID"]]]["IBLOCK_ID"] = $ar['IBLOCK_ID'];
  $arResult["SEARCH"][$arID[$ar["ID"]]]["PICTURE"] = CFile::GetFileArray($ar["PREVIEW_PICTURE"]);
  $arResult["SEARCH"][$arID[$ar["ID"]]]["CATALOG_PRICE_1"]=$ar['CATALOG_PRICE_1']*1;
  $arResult["SEARCH"][$arID[$ar["ID"]]]['PRICE'] = CCatalogDiscount::GetDiscountByProduct(
      $ar["ID"],
      $USER->GetUserGroupArray(),
      "N",
      1,
      SITE_ID
    );

  }
  }
 } ?>

CIBlockElement::GetList

In the second parameter, only by ID and the search is set.
Name does not appear at all.
