• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. ((hieu vu) OR (((hieu su) OR (hieu sau)))) cham soc van anh de cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. ((hieu vu) or (((hieu su) OR (hieu sau)))) cham soc van anh de cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. ((hieu vu) or (((hieu su) OR (hieu sau)))) cham soc van anh de cua triet*.
