Boolean Operators are words or marks typed in some search engines' search box to show specific webpages with certain phrases or words together or omitted. The term is derived from Boolean logic.

Common Operators

Using the examples in a search for Car, Ford: AND -- When typed between two words show webpages that have the words "car" and "Ford".

NOT -- When typed between two words (such as Car AND Ford) only show webpages that have the words "car", but not "Ford".

OR -- When typed between two words, the search results will show all webpages with the words "car", but not "Ford".

Combinations can also be achieved, such as "car AND Ford NOT Gerald". This will show all webpages with the words "car" and "Ford", but omits those that also include the word "Gerald".

Quotation Marks -- Narrows down a search of webpages by only showing specific words in order. Typing "Ford cars" will produce a search showing webpages with the exact phrase and order "Ford cars".

Wildcards are symbols that can be included in a search.

• The percent sign (%) in a search will replace the sign with another letter. Example, searching for "For%" will show all webpages with the word "For" plus replace the % with other letters (such as Ford, Fort, and Fork)
• The asterisk (*) will search for the typed word plus any combination of letters thereafter. Typing "Fort*" may search for "fortification,", "[[Fort
