trong van » trong cac
dang cong » dung cong
van dang » van dong, van dung, van nang
tac than » tac thanh, tac nhan, bac thanh

• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (mot chieu)) sang - hanh trong van dang cong ((tac than) OR (tam than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (mot chieu)) sang - hanh trong van dang cong ((tac than) OR (tam than)) cau*".
