• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((nhieu tang) OR (hieu lang))) OR (chieu sang)) - hanh mang va tong cong dang toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((nhieu tang) OR (hieu lang))) or (chieu sang)) - hanh mang va tong cong dang toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((((nhieu tang) OR (hieu lang))) or (chieu sang)) - hanh mang va tong cong dang toan tap*.
