    Description

      The current problem is an IndexReader and IndexWriter cannot be open
      at the same time and perform updates as they both require a write
      lock to the index. While methods such as IW.deleteDocuments enables
      deleting from IW, methods such as IR.deleteDocument(int doc) and
      norms updating are not available from IW. This limits the
      capabilities of performing updates to the index dynamically or in
      realtime without closing the IW and opening an IR, deleting or
      updating norms, flushing, then opening the IW again, a process which
      can be detrimental to realtime updates.

      This patch will expose an IndexWriter.getReader method that returns
      the currently flushed state of the index as a class that implements
      IndexReader. The new IR implementation will differ from existing IR
      implementations such as MultiSegmentReader in that flushing will
      synchronize updates with IW in part by sharing the write lock. All
      methods of IR will be usable including reopen and clone.
