This is not enough, it is necessary for the JavaScript on the page to understand that the text in the field has changed.
After inserting, make the handlers that the site set for this field work:

document.querySelector('#search').dispatchEvent(new Event('input'));
document.querySelector('#search').dispatchEvent(new Event('change'));
