xkcd plugin not working

[LoLei]

The xkcd plugin is not working properly.
It often returns nothing when supplying the exact comic title or comic ID.

Apparently it uses ohnorobot for search results, but that itself is not working.
E.g.: http://www.ohnorobot.com/index.php?s=wisdom+of+the+ancients&Search=Search&comic=56 should return https://xkcd.com/979/. But it returns nothing.
It also has only 1705 comics in its archive, but even older comics are not found.
I cannot find the source for ohnorobot, it might be closed-source.

I propose these alternatives:

• python-xkcd - supports retrieving comics by ID
• relevant-xkcd - returns multiple results based on relevancy (searches more than the title) (example)

Unfortunately I couldn't find a solution that returns a result based upon an (exact) title search. But maybe either of those could be made to do that.
