Steps in online searching:

Boolean Operators for searching within the databases:

-Identify search terms from your topic, which you will use while searching the databases

-Use Boolean Operators to combine your terms for better search results:

AND – Narrow your search results. "I want only documents that contain both words."

OR - means "I want documents that contain either word or both in the record."

NOT- NOT logic is used to exclude a particular term. We retrieve only records in which ONLY the first term is used, but exclude the second term.
