Google has updated the way it serves up results in response to search queries. This update is designed to work out whether a person wants up-to-date results or historical data.
Google estimated the alterations to its core algorithm would make a difference to about 35% of searches.
The changes try to make results more relevant and beef up features which Google believes set it apart from rivals.
Microsoft’s Bing search engine emphasises social search and is reported to be growing fast in the US.
