• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("cost of _ healthy dies") OR ("cost of _ healthy ties"))) OR ("cost of _ healthy diet"))) OR ("cost of _ healthy adults")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"cost of _ healthy dies\") OR (\"cost of _ healthy ties\"))) or (\"cost of _ healthy diet\"))) or (\"cost of _ healthy adults\"))".
• Removing quotes may allow a broader search: (((((( cost of _ healthy dies ) OR ( cost of _ healthy ties ))) or ( cost of _ healthy diet ))) or ( cost of _ healthy adults )).
• Adding a wildcard symbol may retrieve word variants: (((((("cost of _ healthy dies") OR ("cost of _ healthy ties"))) or ("cost of _ healthy diet"))) or ("cost of _ healthy adults"))*.
