During the add (in DirectUpdateHandler2) docs are kept track of, and during a commit they are checked for dups. That code has been very well tested though, and I've only seen duplicates on a JVM crash/restart. That's because docs are added to the index, but Solr never gets a chance to remove the duplicates (and that info is only kept in RAM). Lucene can now handle this (updating) in an atomic fashion, so we should probably start using that. -Yonik
