• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (hieu quang)) - hanh tang cua bang ((cong hai) OR (cong thai)) quan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (hieu quang)) - hanh tang cua bang ((cong hai) OR (cong thai)) quan cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (hieu quang)) - hanh tang cua bang ((cong hai) OR (cong thai)) quan cap*.
