Self-test On Boolean Operators (And, Or, Not) - Quiz

Boolean operators are the words "AND", "OR" and "NOT". When used in library databases (typed between your keywords) they can make each search more precise - and save you time. Take this test on Boolean Operators to know more about it.


Questions and Answers
  • 1. 

    All of the following are Boolean Operators: AND, OR, NOT.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the operators AND, OR, and NOT are indeed Boolean operators. Boolean operators are used to combine or modify the results of Boolean expressions, which can only have two possible values: true or false. The AND operator returns true if both operands are true, the OR operator returns true if at least one operand is true, and the NOT operator returns the opposite value of its operand. Therefore, all three operators mentioned in the statement are valid Boolean operators.

    Rate this question:

  • 2. 

    The operator AND, when used to link two concept terms (e.g. children and violence) will retrieve only those records that contain both concept terms.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    With Boolean AND, the database or search engine looks specifically for the presence of BOTH specified words, children and violence, in each record.
    AND = Both

    Rate this question:

  • 3. 

    Using the operator AND to combine concept terms is a good way to increase the number of records retrieved in a search. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    With Boolean AND, BOTH terms must be present in the record. It is reasonable to assume that imposing this specific restriction on the search will result in fewer records.

    Rate this question:

  • 4. 

    The operator OR, when used to link two or concept terms will retrieve fewer records because both terms need not be present in each article.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    With Boolean OR, the database or search engine is instructed to look for the presence of EITHER term in each record. No specific restrictions have been imposed on this search.
    OR = Either.

    Rate this question:

  • 5. 

    The operator NOT is another way to broaden a search or retrieve more records.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Boolean NOT imposes a restriction on the search, to EXCLUDE any records that contain the specified term.
    NOT = Exclude

    Rate this question:

  • 6. 

    The following search statement will exclude any records that contain the term "poodle." (dogs OR canines) NOT cats.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    This search query does not specify that poodles are excluded. If an article about poodles contained the word "dog," this record would be retrieved. Only those records that have the word "cats" in them would be eliminated.
