AI Search

Peter Norvig, Director of Search Quality at Google, tells how Google is using AI to provide better search.  He stated that Google has developed a lot of AI functionality that is still sitting on the shelf because it is too costly in terms of query response time to implement.

Personalized search is a growing trend for the major search engines.  Chris Sherman described Google’s Personalized Search in this article:

Google's personalized search reorders search results based on your history of past searches, giving more weight to topics that interest you.

This means that if you search for "fly fishing" your future results for a search on "bass" will be more heavily weighted toward fishing than the musical instrument, according to Avni Shah, Google product manager.

Personalized search also maintains a history of your searches on Google, allowing you to revisit pages you previously viewed by scanning through your history.
