why doesnt the search engine support numbers?

as the title says

why doesn’t a query for uv return anything?

it is probably because it has a list of things that it keeps track of, and you can only search for them.

however, if one can modify that list there are certainly a lot of things to add to it
blender versions, builds, terms [sss, uv, …]… yeah

AFAIK, it doesn’t return anything for UV because it’s too short of a word.

SSS works because it’s 3 letters long (which seems to be the lower limit).
