• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu tinh)) - thanh tung cua vat cong ((san toan) OR (dan toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu tinh)) - thanh tung cua vat cong ((san toan) OR (dan toan)) cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chieu tinh)) - thanh tung cua vat cong ((san toan) OR (dan toan)) cao*.
