Grant Ingersoll commented on LUCENE-2215:
-----------------------------------------
bq. Let's be careful about the semantics here Grant. Most if not all
applications implement paging indeed, but I believe only FEW actually store
user contexts between searches. PagingCollector relies on the application to
store the lowest ranking doc that was returned previously, which means storing
context between user's searches.
I think, assuming the math plays out, that once you show the gains to be had
here, esp. for deep paging, storing an int and a float is trivial. If they are
implementing paging, they are already keeping state about what page they are
on.
bq. Now they will need to think "where do I get this low score from?"
Sorry, but If that is that hard to figure out, then I don't see how they have
any business writing a Lucene application to begin with. A simple javadoc that
says these two values are taken from the last result of the previously seen
page should do the trick
At any rate, let's put up the patches and find out instead of debating. I
should have time today to do mine.
