• If you are trying to use Boolean operators, they must be ALL CAPS: (( materi belajar dan berbagi dasar di ) OR ( mari belajar ((islam dan) OR (islam di)) edi tri ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( materi belajar dan berbagi dasar di ) or ( mari belajar ((islam dan) OR (islam di)) edi tri ))~".
• Adding a wildcard symbol may retrieve word variants: (( materi belajar dan berbagi dasar di ) or ( mari belajar ((islam dan) OR (islam di)) edi tri ))*.
