Stefan, Thanks very much for your quick reply.
Actually I have to write a CustomDataImporter class to full-import data and index them all. So it should be done in java code and schema.xml. When I write a CustomDataImporter, I have to implement a nextRow() method, which return a map<String,Object>. And also schema,xml have a multiValued label for each field. I am wondering how could I utilize it. I believe there must be several ways to make it multi-valued, using analyzer or copyField. I am finding a efficient and easiest way that I don't have to change data format.
