• If you are trying to use Boolean operators, they must be ALL CAPS: (( di tata negara negara ((tahap dan) OR (tahu dan)) ) OR ( mari belajar a mini dunia di ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( di tata negara negara ((tahap dan) OR (tahu dan)) ) or ( mari belajar a mini dunia di ))~".
• Adding a wildcard symbol may retrieve word variants: (( di tata negara negara ((tahap dan) OR (tahu dan)) ) or ( mari belajar a mini dunia di ))*.
