Search engine is the most important tool
for finding information from Internet. All of us use
it in varying degrees. Usually, we search for information
using one or two search engines (e.g. AltaVista, Google)
or directories (e.g. Yahoo). But these search tools
have their limitations:
-
None of them cover all pages on
the Web.
-
There is a long lead time (often
weeks) to index new pages.
-
They generally cover the Web only,
excluding other important information sources
on the Internet.
-
They usually index only "static"
Web pages, excluding the large body of information
stored in databases on Web sites and retrieved
on demand.
-
They employ limited "intelligence"
in their search - mostly relying on occurrence
or non-occurrence of search word.
However, even within its limitations
- search engines can provide far more useful information
provided you invest some time and effort in understanding
how they work and learn tips on getting the most out
of them. The problem is few people take the time to
read and understand the directions. Consequently,
some Internet users wind up with thousands of irrelevant
matches simply because they don't know how to conduct
an accurate search.
While we shall discuss how to refine
your searches and extract more from search engines
in future issues - here is one technique to quickly
get more from your search - by using meta search engine.
Meta search engines query multiple search
engines on the Web simultaneously and compile the
results for you. Most meta search engines allow you
to search web-pages, files, music, images etc.
So, instead of going through each search
engine - use meta search and get results from multiple
search engines at one place.
