Perhaps you should try some spelling variations:
hari belajar » mari belajar, mari belajara, cara belajar
belajar dan » belajar anak, belajar mata
kajian dan » kajian al, harian dan, kajian di
usul dini » usia dini, usul dan, usai dini
dan asal » dan pasal, dan amal, dan asam
kajian a » kajian al, kajian di, kajian qs

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: (( hasil belajar dan asal usul dini ) OR ( hari belajar ((kajian a) OR (kajian dan)) dunia dan ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( hasil belajar dan asal usul dini ) or ( hari belajar ((kajian a) OR (kajian dan)) dunia dan ))~".
• Adding a wildcard symbol may retrieve word variants: (( hasil belajar dan asal usul dini ) or ( hari belajar ((kajian a) OR (kajian dan)) dunia dan ))*.
