SOLR-1632 covers the distributed IDF issue. Plans right now are to include this in Solr 5.0 when it is released. https://issues.apache.org/jira/browse/SOLR-1632 The only way to have a reasonably accurate distributed score currently is to load your shards as evenly as possible. A good way to do this is to use the hash value of the uniqueKey field as the deciding factor for which shard gets the request. This is what SolrCloud does if you let it handle the routing.
