我需要用常用词来获取所有记录。但这对我来说太难了。
record(id(1),myString([exchange, company, price]).
record(id(2),myString([share_current, change, industry, company]).
record(id(3),myString([currency, trans_share, type, and]).
record(id(4),myString([price_max, price_min, share_current, work]).
结果：
myString([exchange, company, price]
myString([share_current, change, industry, company]
myString([price_max, price_min, share_current, work]
