• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach ty)) nang ((o hoi) OR (o hai)). hieu ve cam xuc van hanh hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) OR (sach ty)) nang ((o hoi) or (o hai)). hieu ve cam xuc van hanh hai cua te".
