• The words AND, OR and NOT may confuse the search; try adding quotes: "%22jews %((2((f education) OR (deaf education))) or (((f education) OR (deaf education)))) %21 germany %13 bavaria %((2f history) or (imf history))%22".
• Adding a wildcard symbol may retrieve word variants: %22jews %((2((f education) OR (deaf education))) or (((f education) OR (deaf education)))) %21 germany %13 bavaria %((2f history) or (imf history))%22*.
