5. GOOGLE SEARCH
Google Search,
commonly
referred to
as Google Web
Search or
simply Google, is
a web search
engine developed
by Google.
It is the most-
used search
engine on
the World Wide
Web, handling
more than three
billion searches
each day.
Google's rise to
success was
largely due to a
patented algorith
m called PageRan
k that helps rank
web pages that
match a given
search string.
Google's search
engine normally
accepts queries as
a simple text, and
breaks up the
user's text into a
sequence of
search terms,
which will
usually be words
that are to occur
in the results
Google
applies query
expansion to the
submitted search
query,
transforming it
into the query
that will actually
be used to
retrieve results.
Google's stated
mission is to
"organize the
world's
information and
make it
universally
accessible and
useful."
It is the No.1
search engine in
the world, a
position that has
generated
criticism and
concern about the
power it has to
influence the flow
of information on
the Web.
