"You can't expect to hit the jackpot if you don't put a
few nickels in the machine."

Metasearch engines do not crawl the web compiling their
own searchable databases. Instead, they search the databases
of multiple sets of individual search
from a single site and using the same interface. Metasearchers
provide a quick way of finding out which engines are retrieving
the best results for you in your search.
Metasearch engines present the results of their searches
in one of two ways:
- Single List.
Most metasearchers display multiple-engine search results
in a single merged list, from which duplicate entries
have been removed.
- Multiple Lists.
Some metasearchers do not collate multiple-engine search
results but display them instead in separate lists as they
are received from each engine. Duplicate entries may appear.
Metasearch engines can give you a fair picture of what's available
across the Web and where it can be found.
Metasearchers are very fast.
More and more, metasearch engines seem to be casting smaller nets by relying on
subject directories and pay-per-click engines for their Web results.
Metasearch engines don't offer
the "salad bar"
of search options that individual search engines do.
When you initiate a keyword or phrase search on a metasearch
engine, you are usually at its mercy as far as how the search is
configured and conducted.
Although metasearch engines query a number of individual
search engines, not enough query
one of the largest and most popular search engines
on the Web. (Note:
Use metasearchers when you are in a hurry.
Metasearch engines are useful in obtaining a quick
overview on a subject and/or unique term.
when you are conducting a relatively simple search and also
when you are not having any luck pulling up documents in your
