• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (vu sach)) ky nang xa hoi. hieu vien da bao ((va dinh) OR (van dinh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (vu sach)) ky nang xa hoi. hieu vien da bao ((va dinh) OR (van dinh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (vu sach)) ky nang xa hoi. hieu vien da bao ((va dinh) OR (van dinh)) vi cua triet*".
