• If you are trying to use Boolean operators, they must be ALL CAPS: (( mari belajar lari di ((dunia 1) OR (dunia 4)) ) OR ( 1 permasalahan gangguan pada usaha dini ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar lari di ((dunia 1) OR (dunia 4)) ) or ( 1 permasalahan gangguan pada usaha dini ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar lari di ((dunia 1) OR (dunia 4)) ) or ( 1 permasalahan gangguan pada usaha dini ))*.
