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