Internet Search Engines What are they? Internet
search engines are complex computer programs (also called spiders, robots,
and worms) that search the Internet for the words you type into the search
box. The results are returned in a ranked order. Each search engine uses a different ranking
system. Some use the number of word
occurrences, popularity, sponsored links, or another means. Each search engine also searches different
parts of the Internet and different elements of a web site. Every search engine works differently. This means one of the most important
aspects of searching (aside from typing in the right words) is knowing how the search engine works. Which search engine
should I use? Here are some
suggestions:
Google is the search
engine that librarians recommend most often.
It ranks web sites according to web popularity. The sites that have the most links come up
first. This works well for finding
information that is relevant (closely related) to the search topic.
Vivisimo is a meta-search engine. This
means it searches more than one search engine (for instance Lycos, Altavista, MSN) for your search terms. In addition to ranking web sites, Vivisimo clusters them by topic so you can find groups of
sites that are closely related. How do I search?
AND Example: cloning and ethics (Narrower search) OR Example: ethics OR
“moral issues”(Broader search) NOT Example: cloning NOT
sheep (Eliminates words)
Find
the root word ( the letters that different forms of the word share in common) Add
an * (asterisk). To find: history,
historic, histories Use:
histor* How do I print, e-mail,
or save? Once
you locate your information, select File from the top menu, you will
have the option to print, or save as (choose the y:
drive). Ask the librarian for help on
how to e-mail or for any other questions you might have. Go to Google www.google.com How many teaspoons of
