• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (theo chieu)) tinh - thanh trung cap ((nhung dung) OR (nhung phun)) van thanh cha~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (theo chieu)) tinh - thanh trung cap ((nhung dung) or (nhung phun)) van thanh cha~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (theo chieu)) tinh - thanh trung cap ((nhung dung) or (nhung phun)) van thanh cha*.
