• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((thiet tach) OR (chiet tach)) - ((thanh hung) OR (thanh tung)) lam truong dong tan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((thiet tach) OR (chiet tach)) - ((thanh hung) or (thanh tung)) lam truong dong tan than cau".
• Adding a wildcard symbol may retrieve word variants: ho ((thiet tach) OR (chiet tach)) - ((thanh hung) or (thanh tung)) lam truong dong tan than cau*.
