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