Steps to reproduce:
Search using the w!
bang or choose "Search with... wikipedia" from the "More" dropdown
The default expansion provided by Kagi is https://wikipedia.org/wiki/%s
, which only works properly if the search term matches an article title.
Expected behavior:
The correct expansion should be something like https://wikipedia.org/w/index.php?search=%s
which will bring up the article if the search term matches the title, otherwise do a full text search.
