• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky ((mang may) or (tang ma)) hoi. hieu ((ve cam) OR (va cam)) luc va anh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky ((mang may) OR (tang ma)) hoi. hieu ((ve cam) OR (va cam)) luc va anh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky ((mang may) or (tang ma)) hoi. hieu ((ve cam) OR (va cam)) luc va anh di cua te*".
