tan yong » tan hong, tan kong, tan yang
yong lun » kong lyn, yong ben, yong suk
jong min » gong min, song min, song ming
long shu » cong shu, tong shui, long du

• If you are trying to use Boolean operators, they must be ALL CAPS: liang tan yong lun lu ((jong min) OR (sang minh)) long shu ;~.
• Adding a wildcard symbol may retrieve word variants: liang tan yong lun lu ((jong min) or (sang minh)) long shu ;*.
