Haven't got a clue. And I can't have a clue since the answer would be
different if each doc had one field or 100 . About the only
thing I can think of is to try it and measure...
What is the use case where you'll be opening this index just to find
its version? Could you just do that once at progr
what do you think about the overhead of opening the IndexReader just to find

e.g. if you have a large index, say 10M docs, just opening it to find out

Sure, just index a *very special* document with one field that is
shared by no other documents in your index. Put your
custom signature in there.
You can even get it very efficiently with TermEnum if you
don't want to search for it, but searching would also be very
fast. Put, say, two fields in th
Hi:
Is there a way to added custom signature data to a lucene index, e.g data
version etc?
Thanks
