Shai Erera commented on LUCENE-1879:
------------------------------------
Hi Grant - I believe what you describe is related to solving the incremental
field updates problem, where someone might want to change the value of a
specific document's field. But PI is not about that. Rather, PI is about
updating a whole slice at once, ie, changing a field's value across all docs,
or adding a field to all docs (I believe such question was asked on the user
list few days ago). I've listed above several scenarios where PI is useful for,
but unfortunately it is unrelated to incremental field updates.
If I misunderstood you, then please clarify.
Re incremental field updates, I think your direction is interesting, and
deserves discussion, but in a separate issue/thread?
