Lucene version naming of index files

[Bernd Fehling <be...@uni-bielefeld.de>]

Hi list,

a stupid question about the naming of the index files.
While using lucene (and solr) 4.2 I still see files with "Lucene41" in the name.
This is somewhat confusing if lucene 4.x produces files with "Lucene4y".
This also means indexes built with 4.2 or 4.3 are fully compatible with 4.1 ?

Regards
Bernd

No and No.

Its just that the postings format is unchanged since 4.1

Don't try to read anything more into it.
