> I see stuff like: "merge problem with lucene 3 and 4 indices" (from solr
> users list), and cannot even think how to respond to these users because so
> many things can go wrong with IndexWriter.addIndexes(Directory)
> it currently has in its javadocs:
> NOTE: the index in each Directory must not be changed (opened by a writer)
> while this method is running. This method does not acquire a write lock in
> each input Directory, so it is up to the caller to enforce this.
> This method should be acquiring locks: its copying *RAW FILES*. Otherwise we
> should remove it. If someone doesnt like that, or is mad because its 10ns
> slower, they can use NoLockFactory.
