• If you are trying to use Boolean operators, they must be ALL CAPS: %22jews %((2f education) OR (f education)) %((21 germany) OR (2 germany)) %13 bavaria %((tnf 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) OR (2 germany)) %13 bavaria %((tnf history) or (imf history))%22".
• Adding a wildcard symbol may retrieve word variants: %22jews %((2f education) or (f education)) %((21 germany) OR (2 germany)) %13 bavaria %((tnf history) or (imf history))%22*.
