      Description

      It can be beneficial for the ConcurrentMergeScheduler to sometimes not do concurrent merges (i.e. sometimes do a serial merge). When the provided "OneMerge" is small and when the MergeTrigger is FULL_FLUSH (i.e. on a commit), a new searcher would benefit from seeing fewer segments. If index replication is used, this setting can reduce the net replication by merging a little more eagerly sometimes.
