I want to add a search bar to my website. But I'm not there yet.
For now, I use Google's site: functionality to search through pages of my website indexed by Google Search.
Here's how it works.
You simply add the site: keyword followed by your domain name to your search query to filter search results to your domain.
your query site:domain.com
For instance, the friction site:nono.ma search query returns a series of writings on friction from my website at nono.ma.
