You can reproduce this by following these steps or just running the test suite: 1. Create a page called Nobel Prize with content nobel prize 2. Create a page called Noble Gases with content noble gasses 3. Create a page called Noble Somethingelse with contents noble somethingelse Finally, search for "Nobel Prize". Problem: We suggest "Noble Prize" Instead we should: Suggest nothing because the original query provides a better match.
I'm really of two minds with regards to this issue so I'm going to set the priority to low. Sure, the example above is a bit lame. But I just had a search for "pantograph" suggest "photograph" which, honestly isn't too weird a suggestion. Better I had a search for "photograph" suggest "photography" which is actually a great suggestion because that term unlocked far more search results that were relevant to the original query.
So I'm going to mark this one patch to review because https://gerrit.wikimedia.org/r/#/c/78311/ should make this a lot less painful. If it comes back up we'll reopen.
