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