• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((thiet tach) OR (chiet tach)) - thanh hang va thong huong dan ((than cao) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((thiet tach) OR (chiet tach)) - thanh hang va thong huong dan ((than cao) or (toan tap))".
• Adding a wildcard symbol may retrieve word variants: ho ((thiet tach) OR (chiet tach)) - thanh hang va thong huong dan ((than cao) or (toan tap))*.
