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