Bitrix - how to search by product property?

Question

1C-Bitrix

I'm doing a custom search in the catalog. Using the CIBlockElement class, you can get properties by product ID, but I want to do a search by name. How can this be done?
Well, at the same time, the question is, where in this function is the infoblock from which it will pull data is set?

$ID = 56767;

if(CModule::IncludeModule("iblock")):
    $prop=CIBlockElement::GetByID($ID)->GetNextElement()->GetProperties();
endif;

Answer 1

if by name, then something like this

$name = 'название';
$arSelect = Array("*");
$arFilter = Array("IBLOCK_ID"=>IntVal($yvalue), "NAME"=>$name);
$res = CIBlockElement::GetList(Array(), $arFilter, false, Array(), $arSelect);
while($ob = $res->GetNextElement()){ 
    $arFields = $ob->GetFields();  
    print_r($arFields);
    $arProps = $ob->GetProperties();
    print_r($arProps);
}

here CIBlockElement::GetByID no infoblock is specified anywhere, only the element ID is specified
