Christine Poerschke commented on SOLR-5730:
-------------------------------------------
Please find attached a two-part patch against latest trunk:
* Part 1 is to make Lucene's SortingMergePolicy configurable in Solr.
* Part 2 is to allow use of Lucene's EarlyTerminatingSortingCollector via an
optional segmentTerminateEarly=(false|true) search request parameter.
Related linked tickets already completed various preparation work and so the
two patches now then are pretty pure and specific to only the change itself
here.
Reviews, comments, etc. welcome. Thank you.
