• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly ((nang xa) OR (nang ma)) hoi. ((hieu vu) OR (hieu ve)) chat huu ban hanh gi ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly ((nang xa) OR (nang ma)) hoi. ((hieu vu) or (hieu ve)) chat huu ban hanh gi ve triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ly ((nang xa) OR (nang ma)) hoi. ((hieu vu) or (hieu ve)) chat huu ban hanh gi ve triet*.
