• If you are trying to use Boolean operators, they must be ALL CAPS: (("te sach hoc dan nguoi") OR ((("ve cach thieten lam nguoi") OR ("ve cach thi ran nguoi"))))~.
• Removing quotes may allow a broader search: (( te sach hoc dan nguoi ) or ((( ve cach thieten lam nguoi ) or ( ve cach thi ran nguoi ))))~.
• Adding a wildcard symbol may retrieve word variants: (("te sach hoc dan nguoi") or ((("ve cach thieten lam nguoi") or ("ve cach thi ran nguoi"))))*.
