• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - thanh ((trung cap) OR (trung tam)) nhung huong bang ((than cao) OR (thai cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh ((trung cap) OR (trung tam)) nhung huong bang ((than cao) or (thai cao))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - thanh ((trung cap) OR (trung tam)) nhung huong bang ((than cao) or (thai cao))*.
