• If you are trying to use Boolean operators, they must be ALL CAPS: (( ri kajian di berbagai negara jodi ) OR ( ayo belajar ((adi al) OR (adil al)) dua di ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ri kajian di berbagai negara jodi ) or ( ayo belajar ((adi al) OR (adil al)) dua di ))~".
• Adding a wildcard symbol may retrieve word variants: (( ri kajian di berbagai negara jodi ) or ( ayo belajar ((adi al) OR (adil al)) dua di ))*.
