------------------------------------
Hi All,
I need one recoomendation, To solve the same parent child update problem, in
versions 6 & 7, we have written our own UpdateProcessors, Will that be a
definate approach. If yes I would be much happier if some one can review the
same, and provide valuable feedback for that fix
> updating parent as childless makes old children orphans

> if I have parent with children in the index, I can send update omitting
> children. as a result old children become orphaned.
> I suppose separate \_root_ fields makes much trouble. I propose to extend
> notion of uniqueKey, and let it spans across blocks that makes updates
> unambiguous.
> WDYT? Do you like to see a test proves this issue?
