Robert Muir commented on LUCENE-4258:
-------------------------------------
A few things I dont understand:
* when updating a document, how do you know which terms to apply negative
postings to?
* how can the idea of updating "individual terms" work as far as length
normalization information? How will that be reconciled?
In truth I think term is too fine-grained of a level for updates in lucene
because of norms,
only updating whole fields of a document will really work (as then the norm can
simply be recomputed and replaced).
