• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((ve pham) OR (ve phan)) duc ((va dinh) OR (va tinh)) lam cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ((ve pham) OR (ve phan)) duc ((va dinh) or (va tinh)) lam cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ((ve pham) OR (ve phan)) duc ((va dinh) or (va tinh)) lam cua te*.
