A boolean query is a query that uses a boolean conditional.
E.g., an overtime formula would be
(hours-40)(hours>40)
The boolean expression would multiply the first result by 1 if hours is greater than 40, and, by 0 otherwise. This would prevent a negative overtime calculation.
The result would be the same as
=if(hours>40, hours-40,0)

Going into Google and typing a search query which includes "something AND something"
Going into Google and typing a search query which includes "something AND something"
It is the same difference between an OR Boolean and AND Boolean. In an OR query, you are looking for something that matches one of several possible values, while in an AND query, you are looking for something that matches all of several possible values. -- Find the first name of anyone in the USA, or have a last name starting with A. SELECT FirstName FROM Contacts WHERE Country = 'USA' OR LastName LIKE 'A%' -- Find the first name of anyone in the USA that also has a last name starting with A SELECT FirstName FROM Contacts WHERE Country = 'USA' AND LastName LIKE 'A%' The difference between these two is that the first one will return people outside the USA if their last name starts with an A, while in the second query, only people inside the USA with the last name starting with A will be returned. AND will always return the same or fewer values than OR.
AND operation is referred as a boolean product
AND boolean
what is boolean operator
The boolean operator that omits information from the search parameters is the NOT operator. When used in a search query, it excludes specific terms, helping to refine results by filtering out unwanted content. For example, searching for "cats NOT dogs" will return results related to cats while excluding any mentions of dogs.
