chieu sach » chinh sach, chiet tach, chieu sang
cong quang » luong quang, thong quang, duong quang
quang tran » quang tuan, quang trung, quang thanh
tran cau » tran chau, toan cau, ran cau
cua van » cua ban, cua dan, cua can

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - thanh cong ((((cua van) OR (cua vat))) OR (ca dan)) cong quang tran cau.
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - thanh cong ((((cua van) or (cua vat))) or (ca dan)) cong quang tran cau*.
