Perhaps you should try some spelling variations:
ragam lisan » ragam ikan, ragam pilihan, ragam latihan
alam lisan » al lisan, alam pilihan
dan paulo » dan palu
paulo ala » gaul ala
peta dan » data dan, kata dan, cita dan
hati di » mati di, hati dari, hati dan
di peta » ii peta, di pekka

You may be able to get more results by adjusting your search query.

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