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