Perhaps you should try some spelling variations:
lembaga negara » lembaran negara, berbagai negara
mari belajar » hasil belajar
pai lembaga » pada lembaga, dari lembaga, di lembaga
negara 1 » negara di, negara ri
dunia ii » dunia di, dunia 4, dunia 1
anak a » anak 2, anak 3, anak 0
anak 1 » anak 19, anak 10, anak 2

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: (( mari belajar pai lembaga negara 1 ) OR ( ayo belajar ((anak a) OR (anak 1)) dunia ii ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar pai lembaga negara 1 ) or ( ayo belajar ((anak a) OR (anak 1)) dunia ii ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar pai lembaga negara 1 ) or ( ayo belajar ((anak a) OR (anak 1)) dunia ii ))*.
