Which search would return fewer results?
- Cancer or Diet
- Cancer and Diet
Correct Answer

A. Cancer and Diet

Explanation

The search "Cancer and Diet" would return fewer results compared to the search "Cancer or Diet". This is because the "and" operator in the search query narrows down the results by requiring both keywords (Cancer and Diet) to be present in the search results. On the other hand, the "or" operator in the second search query allows for either "Cancer" or "Diet" to be present in the search results, resulting in a larger number of potential matches.

Which Boolean Operator do you use to search for synonyms of a word? (e.g. senior citizen, elderly, aged)
- AND
- OR
Correct Answer

A. OR

Explanation

The OR operator is used to search for synonyms of a word because it allows for the inclusion of multiple terms in a search query. By using the OR operator, the search results will include any of the specified terms, providing a broader range of synonyms to consider.

OR is used to narrow a search, and will look for ALL the search terms?
- True
- False
Correct Answer

A. False

Explanation

The statement is false because the OR operator is used to broaden a search, not narrow it. When using the OR operator, the search engine will look for any of the search terms provided, rather than all of them. This allows for a wider range of search results to be returned.

If you are researching the relationship of obesity to diabetes in teenagers, what search combination better conveys the multiple ways that “teenagers” might be expressed in a database?
- Teenagers AND young adults AND youth
- Teenagers OR young adults OR youth
- Teenagers OR young adults AND youth
Correct Answer

A. Teenagers OR young adults OR youth

Explanation

The correct answer is "Teenagers OR young adults OR youth." This search combination better conveys the multiple ways that "teenagers" might be expressed in a database. By using the "OR" operator, the search will include results that mention any of the terms "teenagers," "young adults," or "youth," allowing for variations in how this demographic is referred to in different sources.
