In conducting a literature search, what technique helps refine the results?

• A. Using search terms in conjunction with boolean operators and filters.
• B. Randomly browsing articles.
• C. Ignoring abstracts.
• D. Reading only one journal.

Answer: (A)

Refining literature search results hinges on combining search terms with boolean operators and applying filters. Boolean operators let you control how terms are connected: AND tightens the search by requiring both terms, OR broadens by including either term, and NOT excludes a concept to remove unwanted results. Filters then narrow the results further by criteria like publication date, language, study design, population, or database limits. Together, these tools transform a large, unwieldy result set into a focused, relevant subset that’s practical to review.

This approach is far more efficient than random browsing, which is unstructured and easy to miss key studies. Ignoring abstracts deprives you of quick, essential cues about relevance, and limiting yourself to a single journal greatly reduces scope and may miss important evidence from other sources.
