When I was a kid, if I didn't know how to spell a word and asked the teacher, a common answer was to tell me to look it up in the dictionary.

As words in a dictionary are sorted alphabetically rather than phonetically, this is unhelpful.

YouTube videos have the same kind of problem, in that you can only easily find the video explaining which dielectric unions suit your problem when already know what those are (to use an example that I had to ask ChatGPT for because I have no plumbing experience even if I did know about galvanic corrosion and therefore immediately understood why they're important once I saw the name).
