• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky lang van hoi. hieu ((ve coc) OR (ve cac)) luc ((gia thanh) or (va tinh)) ca cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky lang van hoi. hieu ((ve coc) OR (ve cac)) luc ((gia thanh) OR (va tinh)) ca cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky lang van hoi. hieu ((ve coc) OR (ve cac)) luc ((gia thanh) or (va tinh)) ca cua tre*".
