Google-search – Find web page(s) that links to a specific page in Google Search

It's interesting that if you remove ~ullman from the site you get your first result returned at the very top of the search results again!

 site:http://infolab.stanford.edu/ filetype:pdf view serializability

Browsing around Professor Ullman's page, I noticed that there were no (live) direct links to the original vs-old.pdf file that was at the top of your original search. I'm guessing that if you are restricting results to Professor Ullman's section of the infolab site, there will be no results returned, whereas there are likely to be other pages in the infolab that contain links to that particular document - which results in that pdf reappearing when submitting a less restrictive search.

There are many ways to accomplish this.

dance class near Andheri, Mumbai, India will return listings above the search results

A second way would be to point your browser to google.co.in then set your location in the sidebar. The closest I got was "Andheri East, Maharashtra" (which seems to be the correct way to phrase it).

Web results itself are harder, how would one check whether a site that has dance classes is located in Andheri East, Maharashtra without checking some location within the text displayed on the site?
