Detecting Google Search Layers with Advanced Search Operators

 
 

The way Google presents search results has always been and always will be a bit of an enigma to all of us. Every now and then, however, a snippet of information slips through the cracks giving us a chance to take a look at its search anatomy. In the example below, we can see a search for “greater than 100 years old”, or “100.. years old“. There are four exceptions in this particular example where the operator did not work as expected:

  1. Wikipedia
  2. News Results
  3. PDF Documents
  4. Movie Database
News Results were not a surprise, but the other three are. This perhaps tells us that Google treats, stores and processes different types of resources in different ways.
