docs: Book search does not seem to index all words

[corneliusroemer]

It appears that the book search function doesn't work properly.

Here for example, I don't get any hits for "after" despite "after" being clearly a word in the docs:

Reproduce with: https://just.systems/man/en/chapter_38.html?search=after

Ahh, that's annoying. We use mdBook, so unless we're doing something weird, this should be reported there.

Seems to be a limitation of the elasticlunar.js module they use for search. Indeed not much you can do.
