• If you are trying to use Boolean operators, they must be ALL CAPS: ho chau tinh - thanh ((trung cua) OR (trung tuan)) nhung cong ((tan hang) OR (tan khang)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - thanh ((trung cua) OR (trung tuan)) nhung cong ((tan hang) or (tan khang)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - thanh ((trung cua) OR (trung tuan)) nhung cong ((tan hang) or (tan khang)) cau*.
