Metasearch Engines Why use a single search engine when you can use a Meta? All web search
engines are based on algorithms -- complex series of lexical orders --
when they are combined, they may actually compete/delete results from
some searches. Combining results from two or more engines assures the
researcher of a more complete list of informative web sites. One disadvantage is that the special functions specific to a particular search engine can be lost with a metasearch engine.
Internet Directories Directories place web sites into categories. The web sites are selected
according to the policies of the group that creates the directory.
Directories can lead you quickly to the best or most relevant sites on
your topic. Search engines tend to return a large number of results
with the most popular or best matches for your words at the top;
directories return fewer but often better results. Most directories
include a search feature in addition to category browsing.
