• If you are trying to use Boolean operators, they must be ALL CAPS: (("tu cach hoc lam nguoi") OR ((("tu cac thu lao nguoi") OR ("tu cac thu sao nguoi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tu cach hoc lam nguoi\") or (((\"tu cac thu lao nguoi\") OR (\"tu cac thu sao nguoi\"))))".
• Removing quotes may allow a broader search: (( tu cach hoc lam nguoi ) or ((( tu cac thu lao nguoi ) OR ( tu cac thu sao nguoi )))).
• Adding a wildcard symbol may retrieve word variants: (("tu cach hoc lam nguoi") or ((("tu cac thu lao nguoi") OR ("tu cac thu sao nguoi"))))*.
