Hey, friends, I got a big problem these days. I want to create vectors from Lucene Index,
but I always get the result "lucene.Driver: Writer: 0 vectors".
I operate follow :
$MAHOUT_HOME/bin/mahout lucene.vector --dir <Path> --field contents  --dictOut <PATH>/dict.txt
--output <PATH>/out.txt --max 50 --norm 2

I use the reuter's data.

Help me ,please !
