updating payloads
Is it possible to update the payloads of an existing index? I having
troubles finding any mention of this on the mailing list archives and it
is not obvious that this is possible from the api. I do not want to
change the size of the payloads - just update the values. My payloads
values depend on values returned from reader.docFreq(). I don't want to
update often - just once - and I would settle for a very hackish way of
doing it if needed. I suppose in the worst case scenario I could update
the .cfs file directly - but now I expose my naivety.
Any pointers are greatly appreciated.
Thanks,
Philip

I think it would be nice with little payload modification tool in the
SVN.

I don't think there is any API support for this, but in theory it is
possible, as long as you aren't changing the size. It sounds like it
could work for you since you just plan to do it offline after indexing
and presumably you don't have anything else going on, right? I think
hacking it is the only way for now. Someone else might have a better
idea, but I confess I haven't thought too much about it.
