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