• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach tham nang xa hoi. hieu ((va cau) or (van hau)) luc ((va danh) OR (va dan)) le cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach tham nang xa hoi. hieu ((va cau) OR (van hau)) luc ((va danh) OR (va dan)) le cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach tham nang xa hoi. hieu ((va cau) or (van hau)) luc ((va danh) OR (va dan)) le cua te*".
