I have a fresh install of Solr 5.2.1 with about 3 million docs freshly indexed (I can also reproduce this issue on 4.10.0). When I use the Solr MorelikeThisHandler with content stream I'm getting different results per shard.
I also looked at using a standard MLT query, but I need to be able to stream in a fairly large block of text for comparison that is not in the index (different type of document). A standard MLT query http://testsolr2:8983/solr/mega/select?q=electronics&mlt.flt=text&mlt.mintf=0&fl=id,score appears to return consistent results between shards. Any reason why the content stream query would be different between shards? Thank you for your help!
