Kranti Parisa commented on SOLR-13289:
--------------------------------------
Tomas et all, thanks for taking this up. This will be super useful in terms of
performance gains.
How does this work for:
- Grouping, Sorting
- Custom scoring via value sources
- Payloads
Is TwoPhaseIterator or custom ranking in collapse/expand mode or in response
writer the way? or have to implement a custom query overriding the createWeight
using ScoreMode.TOP_SCORES?
