Yep, I saw non-programming stuff but my worry is, if they are branding themselves as "better search engine for software developers", that programming-stuff will be weighted higher than non-programming stuff even if the search term has nothing to do with programming (or a tenuous link). Though your search examples seem to prove the exact opposite.
All that said the UI/UX is too frustrating to use (as-in) even if they don't promote programming content over non.
* juice
* v8 engine
* juice
* v8 engine
* juice
so definitely some non-programming searches showing up, unfortunately none of the documentation sources for v8.
