Perhaps you should try some spelling variations:
dan perkembangan » dan pengembangan
perdata telaah » perdata terhadap
telaah dan » teladan dan, telaah al, telaah ulang
wali sanga » wali songo
wali sang » wali san, wali songo, dari sang
ali sang » alice sang, dari sang, hati sang

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: perdata telaah dan perkembangan ((ali sang) OR (((wali sanga) OR (wali sang))))~.
• Adding a wildcard symbol may retrieve word variants: perdata telaah dan perkembangan ((ali sang) or (((wali sanga) or (wali sang))))*.
