Hi Vlad and z64, thanks for the feedback.
I can understand how matching exact strings, especially when they contain punctuation, can be difficult. I actually prefer Kagi's conservative “Sorry no matches” over Google's frivolous “Here’s 150,000 things you didn’t ask for.”
I think the main issue here is that the pages with
plist.bundle (the links I posted above) are not even in Kati's index, which I was surprised by because the sources are Stack Overflow and Github. I tried searching Kagi for the title of those pages as well as searched
site:https://url-of-the-page, both returned zero matches.
Kagi really should index GitHub issues and pull requests, because (as a programmer) those pages often have lots of useful details.
