hanh » phanh, nhanh, hangh, thanh, anh, hinh
ntphanh » ntpphanh, ntpnhanh, ntphangh, ntpthanh, ntpanh, ntphinh, ntthanh, ntphan, ntnhanh

• If you are trying to use Boolean operators, they must be ALL CAPS: (han OR ((hanh OR ntphanh) OR (phangh OR ((phanh OR pphanh) OR (thinh OR khanh))))) dynasty~.
• Adding a wildcard symbol may retrieve word variants: (han or ((hanh or ntphanh) or (phangh or ((phanh or pphanh) or (thinh or khanh))))) dynasty*.
