Need to find something but donĂt know the URL address? A
search engine might be just what you need. A search engine is a Web tool
that helps you find specific sites on the Internet.
All search engines work differently. Some store every word from each site in
their databases. Excite and InfoSeek look for new and changed
sites, and enter all the words of each site into their databases. When you
type in a key word, these engines look up every site containing that
word (full-text searches).
Others store site names and descriptions only, but may also include reviews
or ratings. Most are connected with a directory of services which divide
their sites into categories. They search for addresses containing the key
word in their names or descriptions. Excite and Magellan
provide reviews and ratings of the sites while Yahoo lets people
submit their own descriptions.
