You could try using the org.apache.lucene.index.SlowCodecReader to wrap
your index reader:
SlowCodecReaderWrapper.wrap(indexReader) returns a CodecReader from an
index reader.

Unfortunately I can not use that, because I do not want to copy all the
indexes. Our use case is "archiving" of indexes: we would like to copy to
separate file (and remove) part of the indexes, for example which are more
than a month old. We achieved it by writing a Reader which does the
filtering, and use the writer to write them out.

You can addIndexes(Directory... dirs) -- then you don't have to deal
with CodecReader?

Hi,
we have used lucene 4.7.0 before, we are on the way to upgrade to 5.4.0.
The problem I have is that writer.addIndexes now needs CodecReader and
does
not accept a basic LeafReader what we have.
Is there any efficient way to work around that? How would you do it?
Query
the documents and addDocument one by one? Or can I somehow wrap my
LeafReader in a CodecReader? What is the reason to require CodecReader
and
what is that for? Its documentation seems to be missing, and I could not
find anything on the net either.
Thanks for any pointers in advance,
Robi
