4.3.4 Multiple search engine Internet coverage

“This part needs additional information and improvements and is then not finished
yet.”
Let's go now deeper in our analysis by taking in account search engine which
are not using Google technologies. All developed their own technology and are
sometimes better than Google in some fields worst in the other. We will then have
something like that:

Illustration 12: Search engines coverage

So here is my point the most the search engines are different and the most it
gives you the possibility to discover the web. Here I just put the main actors but we
have also to consider that it exists a lot of small search engines which developed their
own index and have then their own way to process data.
Of course one could say that there is no interest for an European person to
process information on a Chinese or even Russian search engine because Chinese
search engine should of course be better in looking for Chinese information rather
than an European one. It is definitely true if we are speaking about contents such as
texts, but when it is dealing with pictures or video the reality should be totally
different.
On the other hand the day where this European person is looking for Chinese
information he should then be aware that he should use the Chinese search engine
rather than the Chinese version of the European one. And as we can imagine all the
other players: Yahoo, Baidu, Mail.ru have their own Boolean operators and their own
sub search engines. So it comes back to the idea of search engine awareness. The
more you know about them and the most you are increasing your knowledge about
how to get the best out of Internet.
