Perhaps you should try some spelling variations:
seri belajar » teori belajar, cara belajar
mari belajar » hasil belajar
anak semut » anak semua, anak sejuta, anak sehat
dan anwar » wan anwar, dan anak, al anwar
mulia di » dunia di
dan kini » dan kiki, dan kiai, dan klinik
usia di » usia dini, dunia di, asia dim

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 dan anwar ((usia di) OR (mulia di)) ) OR ( seri belajar anak semut dan kini ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar dan anwar ((usia di) OR (mulia di)) ) or ( seri belajar anak semut dan kini ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar dan anwar ((usia di) OR (mulia di)) ) or ( seri belajar anak semut dan kini ))*.
