Bruno Roustant commented on SOLR-11865:
---------------------------------------

Sorry for the delay.

Yes, if you can take it from here, that would be awesome!
 * Getters for defaults: you're right, there is no need. Please remove them.
 * keepElevationPriority as a constant in QEC: good point.
 * keepElevationPriority meaning:
Actually the comment is not right, maybe the sorting has changed since the time 
I wrote this comment. I don't think it is linked anymore to forceElevation 
since the ElevationComparatorSource can be added as a SortField even if 
forceElevation=false when one sort by score.
The point is
- with keepElevationPriority=true, the behavior is unchanged, the elevated 
documents (on top) are sorted by the order of the elevation rules and elevated 
ids in the config file.
- with keepElevationPriority=false, the behavior changes, the elevated 
documents (still on top) are in any order, and they may be re-ordered by other 
sort fields (this will allow the use of the efficient but unsorted 
TrieSubsetMatcher in the other patch).

> The goal is to prepare a second improvement to support query terms subset 
> matching or query elevation rules.
> Before that, we need to refactor the QueryElevationComponent. We make it 
> extendible. We introduce the ElevationProvider interface which will be 
> implemented later in a second patch to support subset matching. The current 
> full-query match policy becomes a default simple MapElevationProvider.
> - Add overridable methods to handle exceptions during the component 
> initialization.
> - Add overridable methods to provide the default values for config properties.
> - No functional change beyond refactoring.
> - Adapt unit test.
