The server evaluates the logical expressions. The name 'Boolean' comes from a mathematician named George Boole, who developed the mathematical theory that all variables have a value of 'true' or 'false.' A Boolean search uses Boolean operatorssuch as AND, OR and NOTto narrow or broaden a search depending on the searchers intentions. We’ve placed his name in the first row as a Subject, and placed the book title in the second row. Additionally, bind rules can be complex constructions that combine these criteria by using Boolean operators. The example below shows how you might search for works about Orhan Pamuk’s novel, My Name is Red. These define how the terms on each row relate to one another. The first drop-down menu in that row lists three Boolean operators – AND, OR, and NOT.

The second row in Advanced Search allows you to add more terms to your search. The Search Strategy Builder is a tool designed to teach you how to create a search string using Boolean logic. Just type out your search terms using the appropriate Booleans.Įxample: philosophy AND history AND mathematics Advanced Search with Booleansįeatures built into Advanced Search help you structure more complex Boolean searches. Boolean operators will help you broaden and narrow your searches when when searching library catalogs, databases, and the web. You can use Boolean operators such as AND, OR, and NOT alongside keywords to create a Boolean string that will refine. When you search using these operators, it is known as a Boolean search. The term Boolean comes from the name of the man who invented this system, George Boole. In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0, respectively. Boolean operators are words and symbols, such as AND or NOT, that let you expand or narrow your search parameters when using a database or search engine. There are no prompts in Quick Search’s Simple interface to suggest you can use Booleans, but you can. Boolean logic is a system of showing relationships between sets by using the operators AND, OR, and NOT. For example, you could add or creator or developer to the search string to include candidates with similar profiles when hiring a content writer. Or you can search more broadly if your criteria are flexible. You can narrow your list to people who have the right experience, job title, live in the right city, and are interested in finding a job soon. In Quick Search, keyword search terms can be combined with Booleans that help you broaden or narrow your search, depending on which operator you use. With the Boolean search, you can create searches that target the most important criteria in your candidate profile.

3.7 Boolean Operators Booleans: AND, OR, NOTīoolean operators are connecting words (AND, OR, and NOT) that link two or more keywords or phrases in your search.
