Description
I had a weird situation where a very specifc search query shows results that don't appear to be using the Lense at all. The results are worse than no lense.
The lense I'm using: https://kagi.com/lenses/mv7d8Ur89wDU1lb2P77thoHHKCaYmhg6
Steps
All I did was:
- Search "!pc check if mouse locked" from the Firefox URL bar.
- This shows results with my "PlayCanvas" lense. (Note that PlayCanvas has a default bang with !pc, my lense overrides that default).
- The results I get are completely irrelevant. They don't use any of the sites in my lense. They're even less relevant than the default no-lense search results.

Expectation
I've used this lense a lot and I've never seen results this far off what I was expecting. I expected at least some of the domains I entered into this lense, I see no relevant domains.
The bug seems relevant to the very specific search query I used. If I just add "test" at the end of my query, suddenly the results are what I expect. In fact, as long as I don't use the same exact query, the results look fine. Which makes me think this is caching related.

Even worse than non-lense results
Even if I turn off the lense all-together, the results still look better than the results I got for "!pc check if mouse locked". I realize I have MDN pinned in the screenshot below, but overall it shows more coding-related results, while my bad lense search was showing a ton of IT/customer support results.
