HackerNews search respects double quotes around your terms as an exact match, as do many other search engines.

For example search for "Amerca" with and without quotes. Without quotes you get content for "America" but with quotes you only get the exact typo match.

		This has been a standard feature for nearly all non trivial search engines for at least two decades. I remember this being a feature when I first used google over two decades ago.

		No idea. When I was looking it up, I did see that advanced searching has to be enabled in Algolia for it to work.
