• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (((lang xa) OR (lang van)))) hoi. hieu van cac duc va hanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (((lang xa) OR (lang van)))) hoi. hieu van cac duc va hanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) or (((lang xa) OR (lang van)))) hoi. hieu van cac duc va hanh di cua tre*.
