Abstract
Since the launch of the Google Search engine, a paying version has been reserved for the enterprise, which allows firms' access to documents in the internal database of Google. Microsoft has now declared war on the famous search engine. It is a very profitable market and Gartner Group forecasts that it will be worth $500 million in 2010. Consequently, Microsoft will launch a new version of its own enterprises search engine, ?Share Point Portal' at the end of the year. Microsoft has underestimated the profitability of the activities focused on the Web for a long time. 80% of its revenues were generated from the sales of its famous operating system, Windows and its Office software. Microsoft has decided to raise a barrier between Google and the net surfers. Its objective is to rule over the web. However, we must not forget that Google is five times more famous than Microsoft with respect to public researches on the web. It has been established that one out of every two net surfers research information via Google.
