• If you are trying to use Boolean operators, they must be ALL CAPS: (( mari belajar ((hrd anwar) OR (r anwar)) usia di ) OR ( seri belajar anak semut dan tip ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar ((hrd anwar) OR (r anwar)) usia di ) or ( seri belajar anak semut dan tip ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar ((hrd anwar) OR (r anwar)) usia di ) or ( seri belajar anak semut dan tip ))*.
