Solr - Join Query返回字段值的数组

Question

我正在尝试基于连接查询获取字段的值数组，但返回第二个表中的所有值。我的预期结果是

{"description":"",
   "id":479,        
   "brand":"Lowepro",
   "mrp":4900,
   "name":"Lowepro Photo Hatchback 16L AW  Camera Bag",
  "brandID":19,         
  "srp":[3773,3547,3685],
  "category":"Camera bags"}

现在的结果是：第二个表中的所有srp值（包含srp值）。

你可以帮助我....？提前谢谢。 Data-config.xml是

<entity name="master_products" pk="id"
  query="select p.* ,b.* ,c.*,d.* from master_products p ,master_brands   b,master_product_categories c,master_affiliate_product_mappings d  where b.id=p.brand_id and c.id=p.product_category_id and d.our_product_id=p.id"
