Boolean Operators (AND, OR, NOT, or AND NOT) are basic words that are used as conjunctions to combine or exclude keywords in a search, resulting in more focused and productive results. This should save time and effort by removing irrelevant hits that would otherwise have to be scanned before being discarded.
They link your search terms together to narrow or extend your results set. AND, OR, and NOT are the three basic boolean operators.
Simple comparisons are used by programmes to aid in decision-making. Boolean logic is an algebraic system in which all values are True or False. True and false values are used to test the conditions on which selection and iteration are based.
The order in which the concepts are processed is defined by brackets. When using Boolean Operators like '(art AND therapy) NOT children,' use brackets to limit the database to articles on art and therapy while excluding those that mention children.
Any expression with a Boolean value is a Boolean expression. The comparisons 3 5, x 5, x y, and Age 16 are examples of Boolean expressions. Because 3 is always smaller than 5, the comparison 3 5 will always return true.
