• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach tu ((nang x) OR (nang ma)) hoi. hieu va ((cac xuc) OR (cam xuc)) ban danh hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach tu ((nang x) or (nang ma)) hoi. hieu va ((cac xuc) OR (cam xuc)) ban danh hai cua te".
