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