A professional nurse is searching for information on vaccination among children in a nursing database. The nurse enters two key words (vaccines, children) into the search interface of the database. However, the nurse is unable to retrieve many records during the search. Which of the following Boolean Operators would be appropriate for the nurse to use with the key words to expand the search?
Not
And
Or
Don't know
The Correct Answer is C
A. Not: This would exclude records containing a specific term, further reducing the results.
B. And: This would narrow the search by retrieving only records that contain both keywords, which may not help in this situation.
C. Or: The "OR" operator expands the search by retrieving records that contain either keyword ("vaccines" or "children"), increasing the number of results.
D. Don't know: This is not a Boolean operator.
