• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((((22german university) OR (nigerian university))) or (lodron university))) or (german university))%22".
• Adding a wildcard symbol may retrieve word variants: %((((((22german university) OR (nigerian university))) or (lodron university))) or (german university))%22*.
