> IndexWriter.addIndexes(IndexReader) needs some improvements:
> * It falsely states that this method blocks any add/delete documents attempts.
> * It merges all input IndexReaders at once, and not e.g. like MergePolicy does at mergeFactor steps. Therefore I think it'd be good to clarify it to the user, and also encourage him to call this method several times if he has many IndexReaders to merge.
> ** And while at it, mentioning that the IR can be opened with termIndexInterval=-1 since we don't need it during merge will be good -- saves RAM.
> I'll attach a patch shortly.
