我正在从RDBMS中编入索引。 我在一张有管道分离值的桌子上有一个栏目,在指数化之后,我想将这些数值转化为多价值领域。 例如,

ColumnA (From RDBMS)
---------------------
apple|orange|banana

我想将这一点转化为:

SOLR Index
------------
Fruit=apple
Fruit=orange
Fruit=banana
问题回答

您使用“Reex Transformer”,可具体指明“By=>

<field column="Fruit" splitBy="|" sourceColName="ColumnA"/>
