4.1/n The addition of a new member here which is only sometimes
applicable got me wondering about possibly having `LTRInterleavingScoringQuery
extends LTRScoringQuery` inheritance.

Review comment:
1/n Instead of having a static `isOriginalRanking(LTRScoringQuery
rerankingQuery)` utility method here we could have a
`OriginalRankingLTRScoringQuery extends LTRScoringQuery` class and replace
`LTRQParserPlugin.isOriginalRanking(query)` calls with `query instanceof
OriginalRankingLTRScoringQuery` expressions.
https://github.com/cpoerschke/lucene-solr/commit/6204ead58f1b6378f26d014dbba062423257f04d
explores that.
In isolation the change appears to be somewhat stylistic only but it would
later (2/n and 4/n) allow for other possibilities too.

Review comment:
2/n
https://github.com/cpoerschke/lucene-solr/commit/be20b3a5a94fece4c8387d41831620a0f9497d39
explores making `LTRQParserPlugin.ORIGINAL_RANKING` private. A stylistic thing
to some extent though it would in future also make it easier to pass in their
own alternative to the special `"_OriginalRanking_"` value as a parameter.

Review comment:
5/n When doing the 4/n stuff a question occurred to me here:
`rerankingQueries[0]` and `modelWeights[0]` are the initial values. If the
query is changed to `rerankingQueries[1]` then should the weight also be
changed to `modelWeights[1]`? (Open question, haven't analysed it further yet
nor tried it out.)

variant was called got me wondering about possibly having `LTRInterleavingQuery

Review comment:
3/n `getScoringQuery` already is renamed to `getScoringQueries` to
reflect the changed signature, how about renaming `setScoringQuery` to
`setScoringQueries` also?
https://github.com/cpoerschke/lucene-solr/commit/2579aee9f2e76321a08754d89630f635ae6899b7
does that plus `SCORING_QUERY` to `SCORING_QUERIES` too.

Review comment:
6/n Also as part of 4/n noticed that here this if-then-set likely need
not be inside the for-loop? The loop runs only once or twice so efficiency wise
no concerns but from code reading perspective it not being inside the loop
would be clearer.
