• If you are trying to use Boolean operators, they must be ALL CAPS: (( mari belajar anak badai saya 2 ) OR ( seri belajar ((baca si) OR (baca di)) dunia ii ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar anak badai saya 2 ) or ( seri belajar ((baca si) OR (baca di)) dunia ii ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar anak badai saya 2 ) or ( seri belajar ((baca si) OR (baca di)) dunia ii ))*.
