Boolean search is a type of search allowing users to combine keywords with operators (or modifiers) such as AND, NOT and OR to further produce more relevant results. For example, a Boolean search could be “hotel” AND “New York”. This would limit the search results to only those documents containing the two keywords.

How do you do a Boolean search on Google?

Combine Boolean Searches and Use Exact Phrases When searching for a phrase rather than a single word, group the words with quotation marks. For example, search for “sausage biscuits” (with the quotes included) to show only results for phrases that include the words together, without anything between them.

Is == A Boolean operator?

A boolean expression is an expression that evaluates to a boolean value. The equality operator, == , compares two values and produces a boolean value related to whether the two values are equal to one another. In the first statement, the two operands are equal, so the expression evaluates to True .

George BooleLearn about: How Boolean operators AND, OR and NOT can refine your search by combining or limiting terms. Boolean logic is a system of showing relationships between sets by using the words AND, OR, and NOT. (The term Boolean comes from the name of the man who invented this system, George Boole.)

How do you use Boolean search brackets?

Brackets are used to define the order in which the concepts are processed. Use brackets when using Boolean Operators such as ‘(art AND therapy) NOT children’ so that the database will only look for articles about art and therapy but exclude those that mention children.

Why do we use Boolean operators?

Boolean Operators are simple words (AND, OR, NOT or AND NOT) 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 eliminating inappropriate hits that must be scanned before discarding.
