• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chiet) OR (hoc thiet)) tach - ((thanh tung) OR (thanh cong)) dat hoang phuong dang thanh cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chiet) or (hoc thiet)) tach - ((thanh tung) OR (thanh cong)) dat hoang phuong dang thanh cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chiet) or (hoc thiet)) tach - ((thanh tung) OR (thanh cong)) dat hoang phuong dang thanh cap*.
