How to conduct Basic Search Strategies?

Through boolean operators (And,Or,Not)

Boolean logic is considered to be a well known search strategy used in search engines and in databases; it helps the user to narrow and broaden his search to get accurate information.

Aand: is used to narrow the search and retrieve records containing all of the terms (both words) mentioned in the search.

Example: Library services AND Marketing.

Or: It broadens the search and retrieves results containing any (or both )of the words mentioned in the search

Example: Management OR Administration.

Not: Narrow the search and retrieve records that do not contain the term following it.

Example: Medicine NOT Herbal medicine.
