Searching the Internet?
Kai Chandler checks out top search engine Google.
Think
of the Internet as a library of information. All you need is a
librarian waiting to help you find what you need. Filling this role
in the internet world is the search engine and one of the top search
engines is Google.
Google
is as close as you can get to an essential tool. Yes, there are
hundreds of alternative web searchers but Google is the best
all-rounder. It’s fast, thorough and relevant. It has over 1.3
billion documents currently indexed and powers 29 million searches a
day.
It’s very fast. A search for Practical PC took a
mere 0.74 seconds. It found a staggering 722,000 pages and of these,
the top three links related to this magazine.
How does Google work so quickly? It uses a search
algorithm called PageRank that was developed at Stanford University.
Rather than merely searching the internet and recording what’s at
different sites, PageRank ranks a page according to how many other
pages link to it.
It also evaluates the page that cast the vote. Links
from high ranking pages weigh more heavily and help to improve the
ranking of pages to which they link.
Rather than employ a vast and expensive
number-crunching computer, Google uses a network of thousands of
low-cost PCs to create a superfast search engine.
So that’s the theory but how do you use Google in
practice?
Select the address field in AOL or Internet Explorer
or other browser.
Enter
the address www.google.com
or for a more UK-centric search, www.google.co.uk
When you see the Google banner screen appear, enter
the text for which you are to search.
After a couple of seconds, you’ll see a list of
links. Click on any that may be relevant. Google places the best
links at the top of the list.
If that’s not what you want, select the Back icon
to return to the list and try again.
Note the numbers at the bottom of the search page
– each is a link to the next page of results.
There’s also an Advanced search capability which
lets you specify the search in a number of different ways.
Although Google is functional rather than trying to
be an all-in-one portal to other services, there’s an element of
whimsy in Google’s approach. Watch out for special holiday logos
eg. the Bastille day logo displayed here.
In common with most search engines, Google has a
facility to submit a URL. This will be of interest to those wishing
to promote their own website.
If you use Internet Explorer, you’ll be pleased to
know that Google has a special toolbar to make using Google even
quicker. Details are on the Google site.
To sum up, if you want to search for anything on
the web, take a look at Google.
