• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((nha lang) OR (nhan lang)) xa hoi. hieu vu cham cuu ((va dinh) or (va dau)) vi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((nha lang) OR (nhan lang)) xa hoi. hieu vu cham cuu ((va dinh) OR (va dau)) vi cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((nha lang) OR (nhan lang)) xa hoi. hieu vu cham cuu ((va dinh) or (va dau)) vi cua viet*".
