On en.wiki, I searched for "kentai kessen" (a typo of "kantai kessen", the Japanese battle plan for World War II). I got results for "kendal kessel", which is neither what I asked for nor what I wanted.
This is working as intended. We recently added some functionality so that if you get zero results but have a search suggestion, then you're automatically shown results for the suggestion instead.
The message shown is "Showing results for kendal kessel. Search instead for kentai kessen." which doesn't really indicate that properly to the user. We should change that message.
