When searching for a keyword in Google News you'll see (if you scroll all the way down) a list of related news searches. This is a new feature that will suggest other search terms based on some automated algorithms, making sometimes connections between specific stories. Example, searching for guns will show the following related searches:
This related news searches feature also shows connections where you wouldn't think there would be any. For instance one of the suggested related searches for guns is OJ Simpson - because he was accused of robbery with a firearm - so Google News already made a connection between guns and the robbery. Plus, Las Vegas hotel is mentioned there too, because that's where the assumed robbery took place. Smart isn't it.
Doing another search for Obama, Google News shows these related searches:
The related searches seem somehow normal, however only 2 of the six related searches actually contain the keyword Obama. I know that people searching for Obama are interested in news about Hillary and McCain, but why do these related searches on the Google News page are so different from those displayed on the normal Google Search page (see image below)?
On the normal Google Search page the related searches are actually popular keywords but closely related to the original keyword you used - however on the Google News page the related searches are keywords that are somehow related with the original keyword, but popular in the Google News search.
Here's an example, when doing a Google Search for Obama you see Obama Muslim as a related search. When doing a Google News search for Obama you don't see Obama Muslim as a related news search, mainly because the other related news searches are more popular than this one. So on Google News related searches primes the popularity in the News section, while on Google Search primes the connection with your original keyword.
