Yahoo improves its search engine

Yahoo improves its search engine Munich: Searches on the Yahoo engine should soon deliver more results, thanks in part to new filter functions, reports the company.   Those new filters could allow a searcher, for example, to limit results to those found on major websites like Amazon or Wikipedia. The company also reports that its filter allows searches by related terms.   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.   IANS
