Searching with kagi (on Desktop, from a German IP) for vcpkg vcpkg_from_github does give me as first result the Wikipedia page for 'Wolfgang Kubicki', a German politician:

I do have en.wikipedia.org pinned, but the article does not contain the term vcpkg - i.e., there is zero overlap between my search terms and the result page. I would consider this a bug.
The second result (the Microsoft.com documentation for vcpkg) should be the first result, the first result should not appear at all.
