Which elements describe efficient systematic search strategies, including Boolean operators, truncation, and phrasing? Provide an example search string.

• A. Rely on a single database with no advanced operators.
• B. Avoid any quotes to not restrict phrases.
• C. Use only exact phrases with no synonyms.
• D. Use Boolean operators, quotes for phrases, and truncation; example: (diabetes OR "blood sugar") AND (control OR management) AND ("clinical trial").

Answer: (D)

Efficient systematic search strategies rely on Boolean operators to connect concepts, quotes to lock phrases, and truncation to catch word variants, which together balance breadth and precision in retrieving relevant studies. The example string shows how these pieces come together: using OR to include synonyms or related terms (diabetes or "blood sugar") ensures you don’t miss studies that describe the concept in a different way. Using AND to combine concepts (the disease concept with a management concept and with a study type) narrows the results to items that cover all the needed ideas. Quoting a phrase ("clinical trial") keeps that exact sequence from being split into separate words, so you retrieve studies specifically about clinical trials rather than any articles that merely mention the words individually. Grouping with parentheses clarifies the logic and sets the order of operations so the search engine evaluates the intended relationships. Truncation, shown as a possible enhancement, uses a wildcard after a root word (for example, diabet*) to capture diabetes, diabetic, and related forms, broadening the search without sacrificing structure. So the approach in the example is strong because it demonstrates key practices—Boolean logic, phrase locking with quotes, and thoughtful term grouping—with truncation as an optional, powerful extension. Relying on a single database, avoiding quotes, or sticking to only exact phrases with no synonyms would miss relevant results or fail to capture the full scope of related terms, making the search less systematic and comprehensive.
