• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty hang ((x hoi) OR (x ho)). hieu ve cham xu ((va hanh) OR (va danh)) lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty hang ((x hoi) or (x ho)). hieu ve cham xu ((va hanh) OR (va danh)) lai cua triet".
• Adding a wildcard symbol may retrieve word variants: vu sach ty hang ((x hoi) or (x ho)). hieu ve cham xu ((va hanh) OR (va danh)) lai cua triet*.
