Research about search vs navigation

In 1997, Jakob Nielsen wrote that more than half of the users use search rather than navigation. Here is an answer from 2012 that says that percent of users using search is between 5% and 30%.

My guess is that when there is more users with less technological knowledge, that would decrease the percent of users doing search rather than navigation.

Is there any recent research about what kind of users prefer search, when users prefer search, in what kind of websites users prefer search etc.?
