      Description

      Today index sorting is a very expert feature. You need to use a custom merge policy, custom collectors, etc. I would like to explore making it a first-class citizen so that:

      • the sort order could be configured on IndexWriterConfig
      • segments would record the sort order that was used to write them
      • IndexSearcher could automatically early terminate when computing top docs on a sort order that is a prefix of the sort order of a segment (and if the user is not interested in totalHits).
