Only a termQuery q=field1:2312, No other conditions.
I try debug now, but can not find out what is the main cost.
Debug=timing output like :

My request is : curl "
http://emr-worker-2:8983/solr/collection001/query?q=v00_s:
15de21c670ae7c3f6f3f1f37029303c9&debug=timing"
I also hope to using debug=true to find out more things，so I added some
sub timer to trace which sub method is slowly.
And found , as above, the "SolrIndexSearch.buildAndRunCollectorChain() "
cost a lot。
（ if I want to find out the answer, I think I have not idea but debug
tracing to deeper into lucene level method.)
*At this moment, I have another question too, why debug time is 6336.0,
which less than QTime=157 ? *
