What are search engines?
They are programs that search documents for specific keywords and return a
list of the documents where the keywords were found (Webopedia).
It is a general form of program but the term has more recently been used to
describe systems like Google and Yahoo that enable us to search on the
World Wide Web.
What are some examples?
How do they work?
Web based search engines are able to function by sending out what is known
as a spider to locate as many documents as possible.
A separate program called an indexer the reads these documents and creates
an index or list based on the words in each document.
Each engine then uses a certain algorithm or mathematical process to create
its final listing so that only meaningful results are returned for each search.
(Webopedia)

Search Suggestions when using Google:
Google is not case sensitive (capitals don’t matter)
Put quotes around groups of words (e.g. “google tips”) this will indicate that
you want to search together and in that order
Use “~” to search for all synonyms of a word (e.g. ~affordable)
Use Googles define command to create a glossary of definitions for that word.
To use this command type define: followed by the word to be defined (e.g.
define calculus)
Try the “I’m Feeling Lucky” button on the main Google page when you want
to save time and you are confident that your keywords will produce the
number one search result.
Use the cached feature for broken search results links or sites that are very
slow in downloading. Cached allows you to see a picture of the site as it was
viewed on the last visit by the GoogleBot.
This can be done by clicking on the arrows to the right of the page name.
Google has some incredible features such as:
Calculator
Simply type calculator in your search box
and a calculator similar to the image on
the right will appear and is fully
functional and expandable.
