Using
Search Engines
Emerging Issues:
In our last column we
discussed different ways to find websites for practice, such as
guessing the URL ("Uniform Resource Locator") for that federal agency
address and exploring the indexes in "Webrings" (http://webring.com)
for foster parent support resources. But what if you can't find
anything useful? Given the size of the web, there is invariably
something out there that may be just be what you need, but how do
you find the needle in the hayfield? Use a search engine. Unfortunately,
most of us don't know how to use one well. They are easy enough
to find: all you need to do to summons the large popular ones is
click on the "search" button in the browser. Yet we often find nothing
or get buried in a hundred-thousand useless websites. Here are some
tips for using search engines in social work practice:
First, a few facts. Search
engines are basically computer programs that make and maintain huge
lists of information. Almost all of the large popular ones such
as Excite (http://excite.com), Yahoo! (http://yahoo.com), Google
(http://google.com), HotBot (http://www.hotbot.com), and AltaVista
(http://altavista.com) are automated. No human is directly involved
in creating and maintaining the lists. To make matters worse, the
people who create search engines aren't social workers and often
have a crummy grasp of what we do. As a result, the larger popular
databases often contain useful information but finding it can be
very frustrating. Really helpful websites such as The National
Law Center on Homelessness and Poverty (http://www.nlchp.org),
the Welfare Information Network (http://www.welfareinfo.org),
or disability empowerment information from TRIonline (http://www.idsi.net/tri/index.htm)
can be easily overlooked.
Next, there are roughly
five different types of search engines, and each has different characteristics.
"Keyword" search engines such as HotBot and AltaVista scour the
web day and night electronically reviewing and indexing new websites.
These are the most current, so if you need up-to-the minute information
on a very specific subject, they are your best choice. "Directory"
engines such as "Yahoo!" and "LookSmart" (http://www.looksmart.com)
compile submitted results into categorical databases. These are
usually not as up-to-date but tend to be better-organized and easier
to use. Most of the popular search engines are moving towards combining
both types, and some such as Excite do "concept searching" as well.
If you look for websites with "involuntary" as a keyword similar
concepts such as "detention" will also be included.
There are two additional
types of search tools available: multi- or meta-engines that look
through the databases of several search engines at one time, and
specialized ones designed for specific purposes. The specialized
ones number in the thousands.
Practice Tips:
Avoid randomly choosing
engines from the "search" feature on your browser. Just forget that
button! Instead, stick to only a few of the engines mentioned in
this column and master their instructions thoroughly. No two search
engines work exactly in the same way, so develop a fine-grained
working knowledge before moving on to new ones. Instructions are
usually in the "help" or "FAQ" (frequently asked questions) part
of the search engine's website. Occasionally, there may even be
a "How to use this search engine" button in plain sight but don't
count on it!
Try the meta- or multi-engines
first. These have two virtues. First, since these search multiple
databases, they make those tedious individual tries - search engine
by search engine - unnecessary. Second, they tend to be more forgiving
when you enter an imprecise keyword or make a goof. One we particularly
like is "Ask Jeeves" at http://askjeeves.com. It will allow you
to search using a sentence in plain English. Savvysearch (http://savvysearch.com)
searches twelve of the larger engines in manageable groupings.
Choose narrow keywords
whenever possible. "Dementia" is OK but "Creutzfeldt-Jakob, Alzheimer's
or Pick's Disease" will get more specific results and a shorter
list. In addition, learn to combine several key words together using
the more advanced search features that many search engines offer.
"Logical operators" such as AND, OR, NOT, and NEAR will help avoid
the avalanche of useless URLs. Other search-delimiting tools such
as quotation marks, parenthetic grouping, wild cards, and other
common tricks will drastically cut down your work. For example,
we entered: gay and lesbian housing resources into AltaVista
and got 2,871,612 hits. The much more specific search: "gay and
lesbian" AND (Housing Resources) entered into AltaVista's "advanced
text search" turned up six.
If you don't especially
like your results and your are after a general concept such
as health administration try one of the categorical directory databases
such as Yahoo! or LookSmart. Yahoo!'s links for health issues will
take you to 11 institutes, 41 organizations and 2 web directories
in three clicks. Instead, if you are after a very precise concept
such as summer camps for HIV+ tees, try the larger keyword search
engines. HotBot found 320 using: adolescent camp HIV+. This
sure beats sifting through the 81,580 URLs turned up by Snap (http://www.snap.com).
Use specialized search
engines whenever possible. Forget to check the mileage when you
transported that infant for adoption from Angola to Evansville?
You can convince your supervisor that it was at least 286 miles
one way by visiting "How far is it?" (http://www.indo.com/distance/).
MapQuest (http://www.mapquest.com) will give you directions. There
is probably a complete listing for all of the vegetarian restaurants
and Burger Kings along the way somewhere too. Visit C|Net's A-Z
list (http://search.cnet.com) for several hundred more specialized
search tools.
Finally, if it is really
important, use more than one search tool!
Websites to Visit:
A specific search engine
for social work:
Dr. Gary Holden’s "World
Wide Web for Social Workers" has a vast and growing directory.
It started out as a meta-list and just kept growing! http://www.nyu.edu/socialwork/wwwrsw
Thirty or so search engines
specifically chosen for social workers:
"Search Tools for Social
Work" lists about thirty search engines and provides guidelines
for selecting specific ones such as engines designed for children,
legal resources, or languages other than English. http://socwork.uindy.edu/links/search1.htm
If you really want to
get good at finding stuff:
Visit "Search Engine Watch". They have a superb website and will
send you an online newsletter describing emerging technologies and
trends.
