• If you are trying to use Boolean operators, they must be ALL CAPS: (((("thu hoach hoi lam nguoi") OR ("te cach noi lam nguoi"))) OR ("tu sach doi hay nguoi"))~.
• Removing quotes may allow a broader search: (((( thu hoach hoi lam nguoi ) or ( te cach noi lam nguoi ))) or ( tu sach doi hay nguoi ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thu hoach hoi lam nguoi") or ("te cach noi lam nguoi"))) or ("tu sach doi hay nguoi"))*.
