ref history » reef history, brief history, imf history
2f history » imf history, etf history, tnf history
25 1945 » 25 1995, 25 1985, 25 1915

• If you are trying to use Boolean operators, they must be ALL CAPS: %22italy %((2f history) OR (((ref history) OR (bief history)))) %25 1945-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22italy %((2f history) or (((ref history) OR (bief history)))) %25 1945-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22italy %((2f history) or (((ref history) OR (bief history)))) %25 1945-1976%22*.
