• If you are trying to use Boolean operators, they must be ALL CAPS: %22jews %((f education) OR (deaf education)) %21 germany %((((13 bavaria) OR (_ bavaria))) OR (ii bavaria)) %((2f history) OR (imf history))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22jews %((f education) or (deaf education)) %21 germany %((((13 bavaria) OR (_ bavaria))) or (ii bavaria)) %((2f history) or (imf history))%22".
• Adding a wildcard symbol may retrieve word variants: %22jews %((f education) or (deaf education)) %21 germany %((((13 bavaria) OR (_ bavaria))) or (ii bavaria)) %((2f history) or (imf history))%22*.
