• If you are trying to use Boolean operators, they must be ALL CAPS: (( hasil belajar 12 lembaga negara 1 ) OR ( ayo belajar dasar anik ((tri tri) OR (tri utari)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( hasil belajar 12 lembaga negara 1 ) or ( ayo belajar dasar anik ((tri tri) OR (tri utari)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( hasil belajar 12 lembaga negara 1 ) or ( ayo belajar dasar anik ((tri tri) OR (tri utari)) ))*.
