bagi obat » bagi umat, baku obat, sebagai obat
saat yang » sarat yang, saat sang, shalat yang
bisu dan » isu dan, bisa dan, ibu 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: (( mater sang wajib bagi obat 259 ) OR ( ayo belajar ((salat yang) OR (saat yang)) bisu dan ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mater sang wajib bagi obat 259 ) or ( ayo belajar ((salat yang) OR (saat yang)) bisu dan ))~".
• Adding a wildcard symbol may retrieve word variants: (( mater sang wajib bagi obat 259 ) or ( ayo belajar ((salat yang) OR (saat yang)) bisu dan ))*.
