• Performing a fuzzy search may retrieve terms with similar spellings: su sach van quang ma hoi. hieu van lam thuoc ((van hanh) or (van anh)) ((vi su) OR (va su)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach van quang ma hoi. hieu van lam thuoc ((van hanh) OR (van anh)) ((vi su) OR (va su)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach van quang ma hoi. hieu van lam thuoc ((van hanh) or (van anh)) ((vi su) OR (va su)) triet*".
