Site search provided by author seems like the best option on the first glance, but sadly in my experience those in-house full-text searches are most of the times way inferior than simple `site:` limited google search. If not in relevance then in speed -- I think it is understandable, one could hardly compete with Google in this field. Two genuine anecdotal experiences: - MDN search used to be super slow, and to this days its results page is not super nice and still slower than Google: In-site: https://developer.mozilla.org/en-US/search?q=mutationObserver https://developer.mozilla.org/en-US/search?q=mutationObserve... Google scoped: https://www.google.com/search?lr=lang_en&q=mutationObserver%20site:developer.mozilla.org https://www.google.com/search?lr=lang_en&q=mutationObserver%... - jQuery API docs search felt the same: slow and slightly confusing compared to GSERP. (Much better now with Algolia, but still prefer Google: In-site: https://api.jquery.com/?s=off https://api.jquery.com/?s=off Google scoped: https://www.google.com/search?q=off%20site:api.jquery.com https://www.google.com/search?q=off%20site:api.jquery.com
