• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tay) OR (sach hay)) lang xa hoi. ((hieu ke) OR (chieu ke)) cau luc va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tay) OR (sach hay)) lang xa hoi. ((hieu ke) or (chieu ke)) cau luc va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tay) OR (sach hay)) lang xa hoi. ((hieu ke) or (chieu ke)) cau luc va hanh vi cua te*.
