• If you are trying to use Boolean operators, they must be ALL CAPS: (((("cost of _ healthy dies") OR ((("cost of _ healthy diet") OR ("cost of _ healthy die"))))) 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 diet\") OR (\"cost of _ healthy die\"))))) or (\"cost of _ healthy adults\"))".
• Removing quotes may allow a broader search: (((( cost of _ healthy dies ) or ((( cost of _ healthy diet ) OR ( cost of _ healthy die ))))) or ( cost of _ healthy adults )).
• Adding a wildcard symbol may retrieve word variants: (((("cost of _ healthy dies") or ((("cost of _ healthy diet") OR ("cost of _ healthy die"))))) or ("cost of _ healthy adults"))*.
