• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (hoc thieu)) manh - ((thanh trung) OR (thanh tran)) van hang nong van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) OR (hoc thieu)) manh - ((thanh trung) or (thanh tran)) van hang nong van toan cao".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) OR (hoc thieu)) manh - ((thanh trung) or (thanh tran)) van hang nong van toan cao*.
