• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky nang ma hoi. hieu ve chat ((luoc van) OR (luoc can)) hanh de cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te sach)) ky nang ma hoi. hieu ve chat ((luoc van) OR (luoc can)) hanh de cua triet*".
