FUTURE of search engines..

During the recent years the search engine seems to change it feathers showing a big threat to google "the largest and most reputed search engine of present date "
recent search engines have come down with some new kind of searching techniques and in recent era they are called semantic search engine.
The difference between normal and semantic search engines is normal engines search the web and results which has got the maximum number of times the usage of written text and web crawler saves the pages it visits .
But in case of semantic search engines ,they are developed so that they understand the meaning behind the entered text and then accordingly searches the web and give us the results .The latest search engine of microsoft "BING" is said to be semantic in nature ,even the KOSMIX is rapidly catching the market revealing the fact that the days of google as no.1 search angine are gone .But there is also some argument behind the fact that ,hits that are excluded by semantic search engines and those are included in normal search engine ,the question is can we afford to loose those hits......well answer varies according to search. If we intend to search for meaningful search we should use semantic search engines and if we want to search for the exact text typed we should better use normal search engine those like of google.hence google is no longer supposed to be the king of search engines...
