AS ANY beginner to the Internet soon discovers, the World Wide Web is as full of
mis- and dis-information as it is with the information that you want. Many newcomers
are put off when their first attempts to look up a subject or document result in
increasingly frustrated hours being sidetracked into irrelevant sites. Becoming familiar
with how to use one of the good search engines can help enormously.
First let's distinguish between the two main types of search tools available. "Subject
Directories" provide a structured index of web sites organised as a hierarchy
of subjects. There might be sections on Arts, Business, Politics, Law and Food. The
entries in these directories are references to web sites accompanied by a short description
and in some cases a subjective rating of the site. Typically these directories contain
references to only a very small proportion of the World Wide Web. However the sites
that they do contain are usually a good entry point to the resources available for
a particular subject.
Web search sites on the other hand offer no such structure. Instead they provide
a way for you to search the whole web for particular words or phrases. In a matter
of a couple of seconds these tools search across hundreds of thousands of web sites.
So, when to use a directory and when to use a web search? If you want guidance on
a subject use the directories, but if you are looking for a more specific piece of
information which you can describe by a distinctive phrase or name then use the web
Examples of good general subject directories include The Librarians Index, Britannica,
Galaxy and Yahoo. The Librarians Index has approximately 7000 sites of very high
quality, Britannica has 150,000 each annotated and ranked by their editors, Galaxy
has 300,000 entries with generally good annotations and Yahoo, probably the most
famous directory of them all, has over 1 million but with rather sketchy descriptions.
Try starting out with the smaller directories and moving on to Yahoo if you fail
to find a good source.
You might also find it useful to try some of the more specialised directories. How
to find the right directory? Use a directory of directories such as search.com.
Popular web search sites include Google, Altavista, Northern Light, Infoseek, FastSearch,
Excite and Go. Everyone seems to have their favourite and it's worth trying a few
to see which suits you best. We would recommend trying out Altavista, FastSearch
and Northern Light. You may want to refer to the searchenginewatch site that compares
features and monitors the performance of most of the major search engines.
The main drawback of using these web search sites is that they often return far too
many results and the majority may be irrelevant to you.
Some tips to improve your searching productivity:
- Read the help section of the search site and learn how to focus your search;
- Use more than one keyword to return a narrower selection;
- Use quotation marks if you are searching for a phrase (eg "human rights");
- Don't use capitalization (unless you are searching for a proper name);
- Check your spelling and consider alternative spellings (eg landmines, land mines,
- Learn to use the "advanced search features" (essential as the web grows);
- Search for words you expect to find in a document, not concepts (background,
As an example, we used Altavista to find web pages about rice production in Cambodia.
Entering in the search "rice production in cambodia" returns every page
with ANY of these words - a daunting 130,000. A more relevant set of results is returned
by the string - +"rice production" +cambodia. This indicates that we want
any pages (documents) that contain BOTH the phrases "rice production" AND
"cambodia". It yields 580 results. Adding "+1999" to the search
reduces this to about 100 references.
The web is currently estimated to contain around one billion pages and that is expected
to increase by ten-fold in just a few years. Each of the major search tools covers
only a fraction of this vast resource, so if you are really searching for an elusive
scrap of information you may need to check through more than one. Fortunately there
are tools that make this very easy: Enter the "meta search engines". These
submit your query to many search sites and combine the results. Try out metacrawler,
infind, dogpile or savvysearch. The current favorite seems to be a downloadable program
called Copernic that has the added advantage of automatically checking to see if
the referenced sites still exist. Copernic also stores your search results offline
on your own computer for future reference.
Finally, you may also want to try a search engine for a particular field of specialization
or even a site. If you want information about John Kerry's recent talks with Hun
Sen, specify a news search in one of the search engines (such as Yahoo or Savvysearch)
and try +John Kerry +Hun Sen +tribunal. If you want to find something you read about
Khieu Samphan in the Post, you can use the search engine on the Post's site.
