• If you are trying to use Boolean operators, they must be ALL CAPS: (( ayo belajar ((dari dan) OR (hari dan)) dunia 1 ) OR ( teori belajar dan anak usia di ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ayo belajar ((dari dan) OR (hari dan)) dunia 1 ) or ( teori belajar dan anak usia di ))~".
• Adding a wildcard symbol may retrieve word variants: (( ayo belajar ((dari dan) OR (hari dan)) dunia 1 ) or ( teori belajar dan anak usia di ))*.
