• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty xang ma hoi. hieu ve cau luc ((ban hanh) or (va thanh)) ((va chua) OR (va chu)) tri~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang ma hoi. hieu ve cau luc ((ban hanh) OR (va thanh)) ((va chua) OR (va chu)) tri*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang ma hoi. hieu ve cau luc ((ban hanh) or (va thanh)) ((va chua) OR (va chu)) tri*".
