• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) OR (sach tu)) sang ma hoi. hieu ha ((nam thuc) or (nam thuoc)) xa danh sai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) sang ma hoi. hieu ha ((nam thuc) OR (nam thuoc)) xa danh sai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach tu)) sang ma hoi. hieu ha ((nam thuc) or (nam thuoc)) xa danh sai cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) OR (sach tu)) sang ma hoi. hieu ha ((nam thuc) or (nam thuoc)) xa danh sai cua te*.
