Perhaps you should try some spelling variations:
kitab pelajaran » kitab peladjaran, mata pelajaran, jawab pelajaran
seri belajar » teori belajar, mari belajar, cara belajar
anak matlab » anak mata, dalam matlab
dunia di » dunia ii, dunia dari, dunia 4
siswa sd » siswa smp, siswa di
fiqih » fiqh, fikih

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: (( seri belajar anak matlab ((dunia di) OR (dunia dan)) ) OR ( kitab pelajaran fiqih siswa sd _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( seri belajar anak matlab ((dunia di) OR (dunia dan)) ) or ( kitab pelajaran fiqih siswa sd _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( seri belajar anak matlab ((dunia di) OR (dunia dan)) ) or ( kitab pelajaran fiqih siswa sd _ ))*.
