can i set 2 or 3 uniquekey in solr?

Question

i got a question when i import datas from mysql, however there should be some repeating records from mysql to solr,so i wandered to set another unique field,like these:

 <uniqueKey>_id</uniqueKey>
 <uniqueKey>title</uniqueKey>

Answer 1

对这个问题, 我没有好的方法, 就是给uniqueKey写上两个值的拼接. 如: <uniqueKey>_id_title</uniqueKey> 值为: 1_测试title , 另一种方法是利用动态字段 动态字段实例
