• The words AND, OR and NOT may confuse the search; try adding quotes: "(( dan dunia penelitian dan ((dr mis) OR (di mis)) ) or ( mari belajar dan sejarah heni dwi ))~".
• Adding a wildcard symbol may retrieve word variants: (( dan dunia penelitian dan ((dr mis) OR (di mis)) ) or ( mari belajar dan sejarah heni dwi ))*.
