I'm going to be a bit pedantic here since "before" and "after" are a little misleading. Perhaps "during" is better. What happens internally is that a list "rows" long is kept (i..e the &rows=### parameter). Let's say &rows=20. A list to hold 20 items is created. The first 20 docs are just put in t

Naveen, The documents are sorted before. Lets say if it was a post sort and you are fetching 10 rows it would have pulled up top 10 rows and sorted it. but that is not what happens in solr it sorts in all available docs as per the query and goves the number of rows as per your requirment. Regards

Never meant to imply that it wasn't memory bound! It _is_ memory bound (or at least can be), it's just that the memory consumed isn't proportional to the number of documents matched, but to the total number of documents in your index. Although that all said, once all the structures are in memory, t

Steve: Surprisingly, the number of hits is completely irrelevant for the memory requirements for sorting. The base memory size is, AFAIK, an array of maxDoc ints (you can find maxDoc on the admin screen). There's some additional overhead, but that's the base size. If you sue DocValues, much of the
