Heads up: reindex trunk/5.x indices

[Adrien Grand <jp...@gmail.com>]

I committed a patch that changes the index format for doc values. As a
consequence, if you have indices that you built with lucene trunk or
branch_5x, you have to recreate them.

Note: if you are using an official release of Lucene, you can safely ignore
this message.

If you've got an index built by an official release, any problems with
reading that index in a compatible major version are bugs.  That
guarantee does not extend to unreleased code in version control-- if you
build an index with branch_5x or trunk code, then update the checkout so
it includes Adrien's change, the index won't work and will need to be
rebuilt.

Thanks,
Shawn

Hi Jack,

 

If you would have read the whole message, the answer would be clear: “Note: if you are using an official release of Lucene, you can safely ignore this message.”

The message was for people who built their own Lucene 5.x or Trunk branch, not using an official release. The index format changed since 5.3, but now it changes again. In fact, only the post-5.3 format changed, which was never released.

Will 5.x releases, x>3, require a reindex? I thought the idea was that only a major release (trunk) would change index format.
