• If you are trying to use Boolean operators, they must be ALL CAPS: (( seri belajar sdi di dunia ii ) OR ( atas pemeran visual ((sosial di) OR (sosial dan)) _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( seri belajar sdi di dunia ii ) or ( atas pemeran visual ((sosial di) OR (sosial dan)) _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( seri belajar sdi di dunia ii ) or ( atas pemeran visual ((sosial di) OR (sosial dan)) _ ))*.
