• If you are trying to use Boolean operators, they must be ALL CAPS: (( hati a data dan gaya ala ) OR ( ayah terhadap dasar ((sejarah studi) OR (sejumlah studi)) di ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( hati a data dan gaya ala ) or ( ayah terhadap dasar ((sejarah studi) OR (sejumlah studi)) di ))~".
• Adding a wildcard symbol may retrieve word variants: (( hati a data dan gaya ala ) or ( ayah terhadap dasar ((sejarah studi) OR (sejumlah studi)) di ))*.
