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