Google Plus and Minus Searching (Implied Boolean Logic)

Google and many other search engines let you use:

•  + plus sign as the equivalent of Boolean AND
•  - minus sign as the equivalent of AND NOT

(Return to Survival Plan for a review of Boolean Logic, if needed)

Caution #1: Do not put a space between the + or the - and the keyword.

  Caution #2: Google's search requires + and - rather than AND, OR and NOT.  If you do not use the signs, Google assumes an AND between your keywords.

Examples:

• +chip +chocolate

• +Neptune -planet

• +automobile +car

  Practice + and -
