• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu nano x hoi. hieu ve cam duc va ((thanh lap) OR (((hanh lam) OR (hanh kem)))) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tu nano x hoi. hieu ve cam duc va ((thanh lap) or (((hanh lam) OR (hanh kem)))) cua te".
• Adding a wildcard symbol may retrieve word variants: su sach tu nano x hoi. hieu ve cam duc va ((thanh lap) or (((hanh lam) OR (hanh kem)))) cua te*.
