Perhaps you should try some spelling variations:
pangeran dan » pengertian dan, peran dan
mari belajar » hasil belajar
secara ratno » secara rata, secara ramah, secara rutin
pangan dan » keuangan dan
dan secara » dan sejarah, ikan secara, daya secara
ratno dwi » ratna dwi, ratna dewi
seri dan » peri dan, seri ikan, seri doa
riset dr » riset dan

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 dan ((pangeran dan) OR (pangan dan)) riset dr ) OR ( mari belajar dan secara ratno dwi ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( seri dan ((pangeran dan) OR (pangan dan)) riset dr ) or ( mari belajar dan secara ratno dwi ))~".
• Adding a wildcard symbol may retrieve word variants: (( seri dan ((pangeran dan) OR (pangan dan)) riset dr ) or ( mari belajar dan secara ratno dwi ))*.
