![]() ![]() For example, a semantic code line or model that states: “If A is 1 and B is 1, then add 1” can be reduced into a series of Boolean logical operators and values. Once you have defined the necessary questions, your Boolean. To put it another way, humans can use Boolean logic formats and operators to boil down the code they write into concepts that approach machine language. Any Boolean search master will tell you the true challenge is knowing which questions to ask. Boolean operators and nesting help you search for combinations of words or phrases processed in a specified order. The use of Boolean logic can help bridge the semantical difference between machine language, which is simply a combination of ones and zeros, and syntactical code language, which includes elements of human written languages. Boolean logic and elements like truth tables used to support logical outcomes also reveal the difference between how humans and how computers “think.” Using the above elements, developers can construct logic gates that direct the flow of computing toward various results. ' ' (quotation marks) Indicates exact multiple-word phrases. Any number of boolean search terms can be connected with these operators to refine your search results. Boolean logic commands are accepted by most search engines and searchable data bases to help the researcher search more efficiently. The operators used to express the relationship are AND, OR, and NOT. Experts add the operators NAND and NOR, which combine one of these operators with a negative NOT operator. What Is Boolean (Search) Logic In a search query, Boolean logic helps us define the logical relationship between multiple search terms. At its core, Boolean logic relies on some very basic operators, such as AND, OR and NOT.
