• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh trong nam dong ((cong tang) OR (cong thang)) ((thanh cau) OR (thanh chau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh trong nam dong ((cong tang) or (cong thang)) ((thanh cau) OR (thanh chau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - hanh trong nam dong ((cong tang) or (cong thang)) ((thanh cau) OR (thanh chau))*.
