logical or boolean operator that creates the intersection set
A fundamental logical operator that retains only the elements that two sets of data have in common.
A logical operator joining two well defined logical expressions into one compound logical expression. The compound expression formed will be TRUE only when both logical expressions on each side are TRUE. Logical operator precedence: Not, And, Or.
AND - retrieves documents which INCLUDE both search terms Example: hypertension AND weight - articles will contain both hypertension and weight
A logical combination of two true or false conditions. The result is true if and only if both conditions are true, otherwise it is false. See the table below. condition 1 condition 2 result false false false false true false true false false true true true
Refers to a logical condition that describes two statements which are both true.
a.k.a.: but, C&P page: Definition: A three-letter word in English which combines simple statements into more complex ones, according to the rule that the complex statement is True if both the simpler ones are true, and False if either of the simpler ones are false.
A Boolean operator that narrows a search by requiring both search terms to be in one document.
Logical operation where the result is 1 if AND ed terms both have the value 1.
Boolean operator, all search keys listed must be present to be retrieved. Syn. All of these
Boolean operator that narrows a search by requiring all search terms be present in the results retrieved because of the search. For example, hot and cold would only retrieve information where both "hot" and "cold" appear. See also operators.
The operator AND combines words and/or phrases, ensuring that both are present in the retrieved records or web pages.
When terms are connected by this logical operator, only those entries containing all of the connected search terms will be selected. May be used to narrow a search. Example: homelessness AND children
The Boolean junctor that is true only if both of its subexpressions are true.
A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels. The logic state of a terminal can, and generally does, change often, as the circuit processes data. In most logic gates, the low state is approximately zero volts (0 V), while the high state is approximately five volts positive.
The Boolean operator used to narrow a search by specifying that the words or phrases connected by AND be present in the retrieved results.
The Boolean AND operator, used by WAIS to indicate that found documents must contain both terms that appear in the question.
An operation that can be executed on two or more binary strings. The AND operation compares bits from each string. If they are both positive, the operation returns true, or "1"; if not, it returns false, or "0". For example (0 AND 0) = 0, (0 AND 1) = 0, (1 AND 0) = 0, (1 AND 1) = 1. Thus, (0011 AND 1001) = 0001.
