Robert Muir updated LUCENE-2215:
--------------------------------
Attachment: LUCENE-2215.patch
I think for this issue, we should just add IndexSearcher.pagedSearch() methods
for paging, passing in the bottom result of the previous page (ScoreDoc
lastBottom).
Note for the first page of results, this means you pass in null for lastBottom
and its doing the same thing as search(), so even if you choose to use this
method your 'page 1 results' will be just as fast as IndexSearcher.search()
Also, its easy to make a ScoreDoc from the int+float so apps that want to keep
this state can probably do so easily (and maybe they benchmark and decide its
only worthwhile to cutover to this once you hit page 3, or 4, or whatever).
I also added a few optimizations to the previous code: specialized
InOrder/OutOfOrder, subtract docBase from the bottom's doc in setNextReader to
remove an add, etc.
I didn't add the methods that take sort, but I think we could do this in a
separate issue.
