Early search engines like Gopher and Archie helped users find information on the nascent internet by indexing files across connected servers (paragraph 1). Modern search engines such as Google and Yahoo now also provide sponsored paid links in search results (paragraph 2). Search engines work by crawling the web to index page contents, storing the indexes, and allowing users to search for words or phrases to return relevant results (paragraphs 3-5).

2. Internet Search Engines Work
● When most people talk about
Internet search engines, they really
mean World Wide Web search
engines. Before the Web became
the most visible part of the Internet,
there were already search engines
in place to help people find
information on the Net. Programs
with names like "gopher" and
"Archie" kept indexes of files stored
on servers connected to the
Internet, and dramatically reduced
the amount of time required to find
programs and documents. In the
late 1980s, getting serious value
from the Internet meant knowing
how to use gopher, Archie,
Veronica and the rest.

3. Serch Engines “Google”
● Recently, search engines
such as Google and Yahoo
have also been providing
"sponsored links"; links that
appear on the first few pages
of the search results and that
are paid for by advertisers.
This means that you may end
up clicking on something that
is not relevant to your search,
but instead actually
advertising. The image
presented here gives you an
example of this on Google.

4. About Search engine
● A search engine is a computer
software, that is continually modified
to avail of the lastest technologies in
order to provide improved search
results. Each search engine does the
same functions of collecting,
organizing, indexing and serving
results in its own unique ways, thus
employing various algorithms and
techniques, which are their trade
secrets. In short, the functions of a
search engine can be categorized
into the following:
● 1. Crawling the internet for web
content.
● 2. Indexing the web content.
● 3. Storing the website contents.
● 4. Search algorithms and results.
