9. What is an internet
search ?
• From the days of ARPANET, today,
Internet has become huge unwieldy
and certainly CHAOTIC
• One funny definition of internet is: It
is a huge library with all the books
lying on the floor without any covers
and the chapter have all been
separated- A CHAOS

10. What is an internet
search ?
• To make sense of the chaos of
internet we have IP address which
is the virtual route to a website.
• IP addresses in itself are not much
of an help-as we may not be able to
get the address of the required
website itself. This problem is
solved by conducting an internet
search.

11. What is a internet
search ?
• An Internet search is done by
using a search engine. A program
that searches documents for
specified keywords and returns a
list of the documents where the
keywords were found
• The documents that are returned
can very easily be accessed by
clicking on the hyperlink

the above-mentioned search engine, putting
the key words “search engines”

20. How a search engine
functions
a search engine works by sending
out a spider to fetch as many
documents as possible. Another
program, called an indexer, then
reads these documents and
creates an index based on the
words contained in each
document. Each search engine
uses a algorithm to create its
indices such that, ideally, only
meaningful results are returned for
each query

21. How a search engine
functions
•A program that automatically
fetches Web pages. Spiders are
used to feed pages to search
engines. It's called a spider
because it crawls over the Web.
Another term for these programs
is webcrawler.

22. How a search engine
function
•Because most Web pages contain
links to other pages, a spider can
start almost anywhere. As soon as
it sees a link to another page, it
goes off and fetches it.
•Large search engines, like Alta
Vista, have many spiders working
in parallel.

23. How a search engine
function
•The key to get good search
results is the “key” word that one
types
•Hence, one has to think not just
about what one is searching for,
but about the word or group of
words that will feature
prominently in the page that one is
expecting to find on the Internet

26. Searching for books
•Google and other search
engines are getting the
world's information online by
bringing books online.
•In this by doing a Google
Book Search one sees links
to those books which are
available online

27. Searching for books
• All these books are scanned copies.
A limited preview of all the books
which are there is available. Some
books without copyright issues are
available virtually for free
• And all the books featured have the
links to the site of booksellers as
well as the order form for those
willing to buy it online

28. Searching for books
• The “Guttenberg Project” is
committed to make available as
much of the printed material as
possible in the virtual world for free
• One can contribute books if one has
a scanner and use all the books that
are available for free

29. Looking for definitions
•To see a definition for a word
or phrase, prefix "define" then a
space, and then the word(s)
you want to get defined. If the
Search engine has seen a
definition for the word or
phrase on the Web, it will
retrieve that information and
display it in the search results

30. Looking for music
•Major search engines such as
google have specialized services for
music. One can select the option at
the home page
•If you enter the name of an artist
into the search box, it will display
user reviews, song titles, and other
useful information related to that
artist in the search results.
