• If you are trying to use Boolean operators, they must be ALL CAPS: (((("united national / security council") OR ("united nation's / security council"))) OR ("unified national / security council")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"united national / security council\") OR (\"united nation's / security council\"))) or (\"unified national / security council\"))".
• Removing quotes may allow a broader search: (((( united national / security council ) OR ( united nation's / security council ))) or ( unified national / security council )).
• Adding a wildcard symbol may retrieve word variants: (((("united national / security council") OR ("united nation's / security council"))) or ("unified national / security council"))*.
