• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) nang xa hoi. ((hieu van) OR (thien van)) nam duc va tinh vien cua triet.
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) or (sai ky)) nang xa hoi. ((hieu van) or (thien van)) nam duc va tinh vien cua triet*.
