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