Distributed IDF configuration query

[Reth RM <re...@gmail.com>]

Dear Solr User Group,

    I am trying to configure distributed idf(global df) to a collection
consisting of 3 shards.
Listed below are the configurations applied, however, the debug-explain
results still show the "idf" computed at shard index level. For example,
indexed total 7 docs,  3 among them had the term "art" and they were
distributed into 3 shards, expected docFreq=3 and docCount=7, but results
were as seen in the screenshot below. Incase if the image is not visible,
please follow the link : here

*Configurations applied*

Added the following stats cache config to solrconfig.xml and reloaded
collection
<statsCache class="org.apache.solr.search.stats.ExactStatsCache"/>

Also executed the curl command:
curl http://localhost:8983/solr/test_news_byte_d_idf/config -H
'Content-type:application/json' -d '{ "set-user-property" :
{"solr.statsCache":"org.apache.solr.search.stats.ExactStatsCache "}}'

 Any pointers regarding what else need to be done as a part of
configuration appreciated.

Hi Reth,
there are some problem in the debug for the distributed IDF [1]

Your case seems different though.
It has been a while I experimented that feature but your config seems ok to
me.
What helped me a lot that time was to debug my Solr instance.
