Search Tips
Effective Searching

- You can enter a literal research question:

retirement "health insurance" - To find studies with specific variables, separate the variables with commas and sort by "Variable Relevance" on the results page.
Search Syntax
- A Boolean "and" is inferred with multiple terms.
- Stemming is automatic; do not use an asterisk.
- Search is not case-sensitive.
- Use quotes for phrase searches; use the minus sign to remove items from results:
