I mentioned it in my response to the other reply, but I've found that the average programmer's Google-fu is actually quite poor, and they would not do that subsequent narrowed search.
Doesn't matter anyway, Google nowadays just ignores some words if it feels like it. Even if you add quotes << "stevia" "iOS" "layout" >> then you're not guaranteed that the pages will have all the words in. Google need a "just show me the results I asked for" button.
