Answer:

b. He can look for relevant articles in the results list from a database search and scan the subject terms.

Explanation:

A Search engine is an internet resource or service that searches for keywords or categories specified by the end user and then displays (shows) a list of website which matches or have informations similar to the query. Some examples of popular search engines are Goo-gle, Bing, Yahoo, etc.

The most efficient and effective search strategy to identify subject terms for a database search is to look for relevant articles in the results list from a database search and scan the subject terms.

In order to improve the speed of retrieval for a search engine, high frequency words such as if, or, and, at, to, etc., which are generally referred to as stop words are filtered out.

However, AND should be used to combine keywords and phrases when using a "subject search" option to search a database for relevant articles.
