You can search the Internet in two main ways

• using a search engine
• using a subject

Search engines use suites of computer programs to scan databases and record the words they find. They then match your search keywords against their files and retrieve information sources that match your search terms.

Typically, the databases behind search engines are very large and often searches retrieve thousands of matches. It is therefore essential to be very specific in your search strategy, both to limit the number of matches and to ensure that the most relevant matches appear first in the results list.
