As the search spotlight has been shifting onto Google and
Microsoft, Yahoo has attempted to claw back some attention by announcing
improvements to its filter functions.
According to Yahoo the new filters allow a searcher, for
example, to limit results to those found on major websites like Amazon or
Wikipedia. It also allows searches by related terms.
Yahoo tells us that the engine's search methods have also
been upgraded. 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.
If you tap in the word 'Paris' 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, however cheap and
easy she is.
