gene bank » gene banks, one bank, genomen bank
wang man » wang yan, wang ban, wang dan
min hong » amin hong, min hyoung, min jeong

• If you are trying to use Boolean operators, they must be ALL CAPS: wang man changed iea ((gene yang) OR (gene bank)) ((min hong) OR (tin hong)) hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang man changed iea ((gene yang) or (gene bank)) ((min hong) OR (tin hong)) hai ;*".
