Subject Re: Pulsing40PostingsFormat in lucene 4.1
Date Tue, 29 Jan 2013 22:53:22 GMT
Pulsing41PostingsFormat was just moved out of core to the "codecs" module.

Still, the worst case (had it been deleted) would be to revive the
code from the past release and put it in your classpath, so old
indices could be read.
