Search engine is a computer program
that does the following:
1.
Allows
you to submit a form containing a Query
that consists of a word or phrase describing the specific information you are
trying to locate on the web.
2.
Searches
its database to try to match your query.
3.
Collates
and returns a list of clickable URLs containing presentations that match your
query; the list is usually ordered, with the better matches appearing at the
top.
4.
Permits
you to revise and resubmit a query.
To use a search engine, you have to
supply a query by entering information into a field on the screen. To be
effective, that is, to have the search engine return a small list of URLs on
your topic of interest, you often need to be very specific. To pose such
queries, you must learn the query syntax
of the search engine with which you are working.
Once you learn to use a specific
search engine’s query language
effectively, you can quickly zoom in on very narrow topics. This is the
advantages of a search engine. The disadvantages are that you have to learn the
query language and you have to learn the search strategy.
The following is a light of popular
search engines.
