To determine which search strategy would find the smallest number of documents, let’s analyze each option:
1. **Depression OR psychotherapy OR antidepressants:** This query will return documents that mention any of the three terms, which could lead to a large number of documents since it's a broad search.
2. **Depression OR psychotherapy AND antidepressants:** This search strategy could yield a moderate number of documents. However, due to the presence of "OR," it may still retrieve documents that contain only depression or psychotherapy without requiring both to be present.
3. **Depression AND psychotherapy AND antidepressants:** This query is the most restrictive because it requires all three terms to be present in the documents. It will likely yield the smallest number of documents since it narrows the scope significantly.
4. **Depression AND psychotherapy NOT antidepressants:** This search will return documents that discuss depression and psychotherapy but exclude any documents that mention antidepressants. While it excludes one aspect, it is still broader than requiring all three terms.
Based on this analysis, the search strategy that would find the smallest number of documents is:
**Depression AND psychotherapy AND antidepressants.**
