    Description

      LUCENE-4571 added a MinShouldMatchScorer: capable of using advance() on subscorers for minShouldMatch > 1.

      However, we didn't yet cleanup the (now dead) minShouldMatch logic from DisjunctionSumScorer: which is now only used for pure disjunctions. This can also give some reasonable performance improvements for in-order collection.
