The AND operator (&& or “and”) The OR operator (|| or “or”)

Boolean Operator OR
will broaden your search results. In this case, using OR will retrieve search results containing either the keywords globalization or human rights. Using the Boolean Operator NOT will narrow your search results.

compare two numbers and return a boolean value
. The relational operators are < , > , <= , >= , == , and != . True if x is less than y, otherwise false.

a form of algebra
which is centered around three simple words known as Boolean Operators: “Or,” “And,” and “Not”. At the heart of Boolean Logic is the idea that all values are either true or false.
Does Google allow Boolean searches?
Boolean methods can be used on any search engine
: Google, LinkedIn, or even Facebook. Boolean is a term used to define the process of combining keywords with words called “operators.” These operators tell the search engine how to use the keywords in the search. Operator word examples are AND, NOT, and OR.

operator checks whether two variables point to the same object in memory
. In the vast majority of cases, this means you should use the equality operators == and !=

Which is a logical operator?
A logical operator is
a symbol or word used to connect two or more expressions
such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.
