4.3.3 Single search engine Internet coverage

“This part needs additional information and improvements and is then not finished
Here is a more optimistic representation of Google Internet coverage I made
in order to show that Google is not the Internet and that even within Google's sphere
Internet users cannot access to all the information:

Illustration 10: Google's Index coverage

Google dependent people are not only using Google when making research but as
well Google partners all symbolized by the sign:
Powered by Google means according to an IT company called Alacra33:
Alacra uses Google Search Appliances to create the Alacra Compliance Web. The
use of Google Search Appliances combines the power of Google search technology,
including the ability to find the highest quality and most relevant documents, with
Alacra's domain expertise in selecting those web sites and pages which are relevant
for AML compliance.
Which means that here you have a partnership working more or less in the same way
that using a Google specialized search engine.
There are thousands and thousands search engines all specialized in a specific
field on the Internet which are using Google technology to search sites such as
Tourism, tutorials...
By using all those specialized search engines you are crawling better the
Google's coverage space.
Illustration 11: “Powered by Google” search engines coverage

As you can see here on this configuration by using specialized search engines
powered by Google you will always browse Google's cyberspace and when we know
that Google is not the Internet we can then ask ourselves how we can get the best out
of Internet.
On January the 11th I went on both websites http://www.aol.fr/ and
http://www.google.fr/ and type the following request 'les moteurs de
recherches' both results on the first page were identical. The only
difference is that Google gave me 3,210,000 results and AOL 290,000
(9% of Google results) so as I developed above AOL is looking at the same place as
Google but is applying more filters. Is it really useful considering that AOL is a
general search engine? The answer maybe be given in their home page at
http://search.aol.com/aol/webhome « The AOL Search engine delivers great search
results, enhanced by Google, plus relevant multimedia results delivered on a single
page-so you can search less and discover more . »34
If you go on http://www.google.com/coop/cse/ you will have a good example
of the search engine powered by Google. You can even create your own one. All is
done by using Google technology and you are just applying your own filter by listing
the websites where you want Google to look inside.
