The words AND, OR, and NOT used to combine concepts or search terms when searching a database for information.

Also called a logical operator. Used in programming to identify AND, OR, NOR, XOR, and NOT operations.

Logical operators, such as AND or OR, that form expressions with binary values, denoted 'true' and 'false', or 1 and 0.

A word (AND, OR, or NOT) that helps you narrow, broaden, or refine the scope of a keyword search. On the Internet, you can use Boolean operators with most search engines.

conjunctions AND, OR, and NOT in logical expressions; named for mathematician George Boole (1815-1864). In library usage, refers to these conjunctions in electronic search criteria. AND retrieves items in which both terms are found wolves and Yellowstone. OR retrieves items in which either term is found woman or women. NOT retrieves items in which the first term is present but the second term is not AIDS not United States.

Special words (AND, OR, NOT, ADJ, NEAR, etc.) used to combine terms in a search statement. Used with Search Tools to refine a search.

Words used to broaden or narrow computer database searches. These include or, and, not, and near.

the connectors AND, OR and NOT that are used to limit or expand a search

When using full-text search to find a topic in Meeting Service Help, a logical operator that indicates a conjunctive (AND), a disjunctive, but inclusive (OR), an exclusionary (NOT), or a proximal (NEAR) relationship between two consecutive search terms. See also full-text search.

a word such as AND, OR and NOT, generally typed in capital letters, that indicates how search terms should be combined in a Boolean search

a computer-programming term for conjunctions like, AND, OR, and NOT which can be used to construct more complex search conditions for a database

a keyword that specifies how to combine simple logical expression s into complex expression s

a keyword that specifies how to combine simple logical expressions into complex expressions

a logical conjunction describing the relationship between two assertions ('and' and 'or' being primary examples)

a mathematical operator based on set theory

Boolean operators, otherwise known as logical operators, are used to construct complex searches in a database. There are 3 logical operators: AND, OR and NOT.

The terms 'and', 'or' and 'not' which are used in online searching.

or Boolean Logic The use of AND, OR, and NOT to refine or expand the possible results in your search.

Boolean Operators are named after the British mathematician George Frederick Boole (1815-1864), who developed a system of logic to show the relationship among terms or concepts. There are three primary Boolean operators, AND, OR, and NOT, and they can be used to group search terms. They are primarily used in keyword searches.

It is word such as "AND," "OR," and "NOT". It is used logically to limit a keyword search in a search string.

A word in all capital letters, such as AND, OR, and NOT, used to combine search items. For example, if you search for ham AND eggs, you would get documents which contain both words; ham OR eggs would look for all documents with ham and all with eggs; ham AND eggs NOT seuss would look for documents with both words, but no mention of Dr. Seuss.

Words like AND, OR and NOT - used to refine searches

Terms used in a search engine, which allow you to limit your hits (sites matching your request), therefore shortening your search time. Built with logical reasoning, using the terms AND, OR, NOT. For example, if you want to find web sites about the St. Louis Cardinals, you could use your Boolean operators thusly: St. AND Louis AND Cardinals NOT birds This will look for sites that have "St.","Louis", and "Cardinals" mentioned on the site, without giving you web sites that talk about bird species.

an operator used in database searching which provides a way to express the logical relationships between concepts. The most common operators are AND and OR, but NOT is also sometimes used.

Boolean operators ('and', 'or', 'not',...) are fundamental elements in group algebra. In our context they are used to define intersections, supersets and exclusions related to database queries.

Boolean Operators define the relationship between words in a search statement. The principal Boolean operators are: AND (intersection) OR (union) and NOT (difference)

Instructions defining how the search keys are to be related to each other. Specifically, AND, OR, NOT. See also proximity operators. Syn. Logical operator

see Boolean connector

In REXX, an operator each of whose operands and whose result take one of two values (0 or 1).

A logical connection between two expressions using (among others) AND, OR, or combinations of these. Boolean operators can be used when entering keywords into search engines to more precisely define the search criteria. Different search engines use various methods for entering boolean operators so it is important to check the HELP or user documentation which is usually provided with the engine. Maury looked up Colorado ski areas on the Web using the AND operator by entering: skiing AND resorts AND Colorado into a search engine form.
