Hoss Man updated SOLR-5463:
---------------------------
Attachment: SOLR-5463.patch
Improvements in this patch...
* Moved cursor param constants to .commons.params.CursorMarkParams
* Added QueryResponse.getNextCursorMark
* switch cloud tests to use QueryResponse.getNextCursorMark
* fixed a small ordering inconsistency between the single core response and
the cloud response
* fix TestCursorMarkWithoutUniqueKey's lifecycle so it plays nicely with
multiple run
* add a custom sorting field type into the tests, leveraging sarowe's work in
SOLR-5354
> Provide cursor/token based "searchAfter" support that works with arbitrary
> sorting (ie: "deep paging")

> I'd like to revist a solution to the problem of "deep paging" in Solr,
> leveraging an HTTP based API similar to how IndexSearcher.searchAfter works
> at the lucene level: require the clients to provide back a token indicating
> the sort values of the last document seen on the previous "page". This is
> similar to the "cursor" model I've seen in several other REST APIs that
> support "pagnation" over a large sets of results (notable the twitter API and
> it's "since_id" param) except that we'll want something that works with
> arbitrary multi-level sort critera that can be either ascending or descending.
> SOLR-1726 laid some initial ground work here and was commited quite a while
> ago, but the key bit of argument parsing to leverage it was commented out due
> to some problems (see comments in that issue). It's also somewhat out of
> date at this point: at the time it was commited, IndexSearcher only supported
> searchAfter for simple scores, not arbitrary field sorts; and the params
> added in SOLR-1726 suffer from this limitation as well.
> ---
> I think it would make sense to start fresh with a new issue with a focus on
> ensuring that we have deep paging which:
> * supports arbitrary field sorts in addition to sorting by score
> * works in distributed mode
