It is sometimes useful to test search engines to
see how they compare on a standard set of tests. You can determine the breadth
of coverage of each
search engine by trying successively more complex queries, find out which sites
have the largest databases, and get a feel for which sites return better
content
for the types of searches that interest you.
For example, the following list of test searches let you compare the breadth
of coverage of four different Internet search engines. You can try several
searches on the same
site, or the same search on different sites, and compare the number and type
of
pages they return.
