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.

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....
Best
Erick
