Dear Erickson: Thanks to your reply.
But if a,b, c are numeric, how can i run range query? And if can ,how about the performance? Thanks in advance. 2011-04-02 袁武 [GMail] 发件人： Erick Erickson 发送时间： 2011-04-02 02:16:55 收件人： java-user 抄送： 主题： Re: How to do Multiple-Cluster Query? You might consider a multiValued field and a positionIncrementGap longer than the longest <a, b, c> tuple. At that point, you can search for phrase queries where the slop is less than the positionIncrementGap. I'm a bit rushed, so if you need more details we can talk later....
