I only knew of the arithmetic mean until I came across the harmonic mean while studying F-scores in binary classification.

To me, the arithmetic mean makes the most intuitive sense, and I can't get an intuitive grasp of the harmonic mean and geometric mean yet. Are there any other areas they are used in?

Have you tried Kagi Search? I've been using it for a while and it's pretty good. The search time seems to be around 0.2s on average, which is noticeable. The search results seem relevant and I like the customizability.

The only downsides are that you have to sign up for their private beta, which takes a while, and that it will be subscription-based upon their official launch.
