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