• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky tang xa hoi. ((hieu va) OR (lieu va)) cau ((luc va) OR (tuc va)) danh lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky tang xa hoi. ((hieu va) OR (lieu va)) cau ((luc va) or (tuc va)) danh lai cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ky tang xa hoi. ((hieu va) OR (lieu va)) cau ((luc va) or (tuc va)) danh lai cua te*.
