Subject [jira] Commented: (LUCENE-770) CfsExtractor tool

Daniel Naber commented on LUCENE-770:
-------------------------------------

I think there's a small issue which is also in IndexReader.main: the javadoc claims that you
need to copy the segments files to make the extracted index work, but that's not enough, you
will also need to modify the segments file because it contains the information whether the
index is in compound format or not.

> A tool for extracting the content of a CFS file, in order to go from a compound index
to a multi-file index.
> This may be handy for people who want to go back to multi-file index format now that
field norms are in a single file - LUCENE-756.
> Most of this code already existed and was hiding in IndexReader.main.
> I'll commit tomorrow, unless I hear otherwise.  I think I should also remove IndexReader.main
then.  Ja?
