    [ https://issues.apache.org/jira/browse/SOLR-1632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15635553#comment-15635553 ] 

blackwing commented on SOLR-1632:
---------------------------------

I've activated distrubted idf. I've two shards for my collection, shard1 contains 1000 docs and shard2 contains 800 doc.

So maxDoc to calculate idf for a particular doc score is 1000+800?
