I agree that the lack of a clear &quot;no pages matched your query&quot; is large part of the problem.   And as your phrasing indicates, it&#x27;s also worth distinguishing between &quot;not in their index&quot; and &quot;doesn&#x27;t exist on the web&quot;.  Google has a very large corpus, but doesn&#x27;t include everything.<p>But the odd part here (and in line with original post) is that there are pages in Google&#x27;s index that include both terms: <a href="https:&#x2F;&#x2F;discussions.apple.com&#x2F;thread&#x2F;7169461?start=0&amp;tstart=0" rel="nofollow">https:&#x2F;&#x2F;discussions.apple.com&#x2F;thread&#x2F;7169461?start=0&amp;tstart=...</a>.  It&#x27;s just that they don&#x27;t start until 40 or so results in.<p>Searching in Verbatim mode without other modifiers seems to create the response that the original post wants:
<a href="https:&#x2F;&#x2F;www.google.com&#x2F;search?q=deluge.app+retina&amp;tbs=li:1" rel="nofollow">https:&#x2F;&#x2F;www.google.com&#x2F;search?q=deluge.app+retina&amp;tbs=li:1</a>
