Question

____ finds records which include one term but not the other. Use NOT with caution! You may exclude valuable records that include both words.

a) AND
b) OR
c) NOT
d) EXACT

Answer 1

The NOT operator is used to exclude records that contain a certain term. For example, to find articles on 'artificial intelligence' excluding those that mention 'self-driving cars,' the query would be 'artificial intelligence' NOT 'self-driving cars.' Boolean operators are essential for refined searches.

Step-by-step explanation:

The operator that finds records which include one term but not the other, specifically excluding records that contain a term you do not want, is the NOT operator. It should be used with caution to avoid missing out on valuable records that might contain both terms.

For instance, to search for information on "artificial intelligence" but to exclude any records that also mention "self-driving cars," you could use a search query that looks like "artificial intelligence" NOT "self-driving cars."

The use of Boolean operators like AND, OR, and NOT can greatly enhance and refine search results, making it a powerful tool for research.
