• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (lieu tinh)) - thanh trung cua nhung dong thanh ((tran cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (lieu tinh)) - thanh trung cua nhung dong thanh ((tran cau) OR (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (lieu tinh)) - thanh trung cua nhung dong thanh ((tran cau) OR (toan cau))*.
