Shai Erera commented on SOLR-5730:
----------------------------------
I was hoping that we'd change solrconfig.xml to support something like a
<mergepolicy> element which will allow you to define a nested MP. That way one
can define SortingMergePolicy by an element like that:
{noformat}
<mergepolicy class="solr.SortingMergePolicy">
<params>
<sort>f1 desc, f2 asc ... </sort>
</param>
<mergepolicy class="solr.TieredMergePolicy">
</mergepolicy>
</mergepolicy>
{nofromat}
This would allow us to define any "wrapper" MPs in a more general way. What do
you think?
> make Lucene's SortingMergePolicy and EarlyTerminatingSortingCollector
> configurable in Solr
