• If you are trying to use Boolean operators, they must be ALL CAPS: (han OR ((hanh OR ntpthanh) OR ((phangh OR phang) OR (phanh OR khanh)))) dynasty*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(han or ((hanh or ntpthanh) or ((phangh OR phang) or (phanh or khanh)))) dynasty*".
