Yahoo has introduced filter functions to its search engine so that the functionality of Yahoo improves. The new filters will enable the user for restricting his results to the major websites such as Wikipedia and Amazon. The option for searches by related items has also been included.
The engine's search methods have also been upgraded, reports Yahoo. It now analyses the search habit of users over a certain period of time to come up with logical connections between past and present searches.
"For example, if the word 'Paris' is input followed by 'flights' or 'affordable hotels', then Yahoo Search understands that a person is looking for travel information and not for gossip about Paris Hilton.
