For each of these records, we will extract the fields by name and store each of the values in a hash keyed on the field name.

对于这其中的每条记录，都将按名称提取字段并将每个字段值存储到与字段名关联的散列中。

Append the value to the hash value keyed on the field name if it already exists, as this will enable the simple print out of every combination of the field no matter which of the fields matched.

如果值存在，则将其追加到与字段名关联的散列值后，因为这样做将启用每个字段组合的简单输出，而不管哪些字段匹配。
