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