   I was thinking along the same lines as this idea and was pointed here by

   I'm not overly familiar with Lucene data structures, but I imagined that in 
the Term Vector we only need the terms, not their positions, these can be found 
from the segment's term dictionary + posting lists. This should limit the index 
size increase.
   
   Strictly speaking, terms and positions can be found without term vectors, 
but it would take too long to look at all the terms in the dictionary.
