bank amin » banks amid, bank aid, bank api
amin hong » min hong, among hong, tin hong
dong nan » dong yang, dong sin, dong bin

• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (dong di)) ya ((haul mapping) OR (gamut mapping)) bank amin hong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (dong di)) ya ((haul mapping) OR (gamut mapping)) bank amin hong hai ;".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (dong di)) ya ((haul mapping) OR (gamut mapping)) bank amin hong hai ;*.
