Robert Muir commented on LUCENE-2073:
-------------------------------------

Uwe, ok, I am currently trying to come up with a way to word this.

Unknowns like the soft hyphen thing and other things word processors, etc might 
do make me really cautious to say something like this...
I don't want someone to unnecessarily reindex, but on the other hand, I don't 
want to see bug report or whatever either.

> We should put this in a spot that is always pretty visible - perhaps even a

> MaintainingIndicesAcrossVersions, or
