Indeed DirectDocValuesFormat had a back-compat break between 4.x and
5.x ... this is expected/allowed (it is an experimental format).
You should be able to do something like this to more forwards:
* In 4.x, open a new IndexWriter, using the default Codec (which is
back-compat)
* Use addIndex
Hi,
you need to add the JAR file lucene-backward-codec.jar to the classpath (or add
it via Maven). It contains the codecs to read pre-5.0 versions.
