Engines
Compared
to search directories, search engines are less
structured and more driven by the commands of the user. For instance,
AltaVista (below) allows the searcher to type in keywords, then searches
the web for pages that match or contain the keywords, much like online
library catalogs operate.
Search engines are most helpful when you are looking for a specific
site or searching for pages on a narrow topic. Also, the more
words you include as keywords, such as in a phrase, the more focused
your search and results should be.
Search
engines are a much more direct way to search for information on the
web than to search in subject directories, and is often much quicker.
To use a search engine, simply click in the blank search field and type
in the keyword or words that represent(s) your topic or interest.
Avoid common words: choose the words that make this topic unique.
That is one way to narrow your results.
Now,
A Word about the Word NARROW...
When
on the Internet, the word narrow
takes on new meaning. In the
world of the web, you have made big progress in narrowing your
search when you have whittled 4,235,861 sites down to 35,499.
Wow! But do you really want to look at 35,498 more sites
than you have to? Narrow, narrow, narrow, any way you can.
Add more keywords, use phrases lumped within quotation marks,
and when all else fails, read the HELP screens. Even
when you find your search produces thousands more pages than you
think you need, often the first few will give you the information
you need. Follow the links to those first few pages before
you try the search again. |
Yahoo and AltaVista are two examples of commercial portal sites, and
there are many, many such sites. You will find that most search
sites such as these contain both subject directories and search engines,
but each search site may have special functions that the others may
not have.
For more information on
specific search engines, see the Internet
Public Library's information on Web
Searching.

Hints
Point and click on the SEARCH button on the Netscape toolbar or
the Internet Explorer toolbar. This button serves as a quick
link to search sites on the Web. |
Don't
try to know about all the search sites. Really LEARN to
use just two or three good search engines. Read the help
screens and don't be afraid to try the site's advanced searching
techniques. |
Search
first for descriptive, specific keywords. When using multiple
keywords that need to appear together in a phrase, such as "single
working mothers", use quotation marks around the keywords. |
Be aware that no index to the web in any subject directory or
search engine is complete. The web is too huge and changes
too quickly for any human or automated mechanism to keep up with
its ever-growing mass. Use multiple search engines and pool
the results. Don't ever give up after only one search-vary
the keywords, narrow, or try a different search engine. |
Finally remember that commercial portal sites are designed for general
users of the Internet, not necessarily students. Having a site
listed at a commercial portal site does not guarantee quality at those
sites. For information about evaluating Web sites, read on!
