Google Related Search Gets An Overhaul

"To better understand and answer your searches for a list, we use a variety of signals to assess what the web collectively thinks are the most significant items associated with your search keywords.

This improvement to related searches reflects our continued efforts to help our algorithms better understand content on the web in the complex ways that humans do, and use that understanding to help you as you search."

1. The "Top References" suggestions are displayed only for very popular queries


2. This feature works best with one or two word (short keywords) search queries


3. If you search for an individual item you will not get a list of related search results. However if you search for a bigger group you are more likely to see a list of similar/related items. For example , if you search for Mark Twain, you won't see names of other authors in the references list. Instead, you have to search for "American authors" and the references suggestion should appear.
