• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (cac ky)) nang ma hoi. hieu ve bao ((luc van) OR (luoc van)) nhan dien cuc thue.
• Adding a wildcard symbol may retrieve word variants: thu ((sac ky) or (cac ky)) nang ma hoi. hieu ve bao ((luc van) or (luoc van)) nhan dien cuc thue*.
