• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (chau tinh)) - hanh hang ca hang nong dan ((phan cau) OR (toan cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) OR (chau tinh)) - hanh hang ca hang nong dan ((phan cau) or (toan cau))".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) OR (chau tinh)) - hanh hang ca hang nong dan ((phan cau) or (toan cau))*.
