> 2. Nim (Programming Language) is not indexed.

You and dom96 (https://news.ycombinator.com/item?id=28013376) both noticed this issue, just two minutes apart. I guess there's some sort of inclination among HN readers testing out a static copy of Wikipedia to search for Nim? :-)

dom96 is a core developer of the language, and author of Nim in Action, so it makes sense for him to look it up. I don't know the OP.

More generally, it appears that any link containing brackets is broken/missing.

This appears to be the issue.

http://static.wiki/en/Gardena does not contain a link to http://static.wiki/en/Gardena_(company) yet https://en.wikipedia.org/wiki/Gardena does.

I noticed if you go directly to the page for Nim, it works.
