More prosaic but if you have a blog etc. you can add a Google programmable search engine: https://programmablesearchengine.google.com/about/

You can also put a DuckDuckGo search box, works well for website search and supports DDG instead of Alphabet.

EDIT: Shameless plug if it gets the author to go with a non-google option https://www.gkbrk.com/wiki/DuckDuckGoSearchBox/
