ETL 505

When reading through the course material I found the term Boolean appearing with out an explanation. Having a not heard of that term before I searched online and found a quick explanation. 

Boolean searches allow you to combine words and phrases using the words AND, OR, NOT (known as Boolean operators) to limit, broaden, or define your search. A good researcher should know how to do a Boolean Search.

"AND" logic

AND : Using AND narrows a search by combining terms.



"OR" logic

OR : Using OR broadens a search to include results that contain either of the words you're looking for.



"NOT" logic

NOT : Using NOT will narrow a search by exclusion. (Some search engines, like Google, recognize the minus (-) symbol, instead of the word NOT).
