The HTMLHyperlinkElementUtils.search property is a search string, also called a query string, that is USVString containing a '?' followed by the parameters of the URL.
Modern browsers provide URLSearchParams and URL.searchParams to make it easy to parse out the parameters from the querystring.
string = object.search; object.search = string;
// Let an <a id="myAnchor" href="https://developer.mozilla.org/en-US/docs/HTMLHyperlinkElementUtils.search?q=123"> element be in the document
var anchor = document.getElementById("myAnchor");
var queryString = anchor.search; // Returns:'?q=123'
// Further parsing:
let params = new URLSearchParams(queryString);
let q = parseInt(params.get("q")); // is the number 123
