`MergePolicy.MergeSpecification` `LogMergePolicy.findMerges(MergePolicy.MergeTrigger mergeTrigger, SegmentInfos infos)` Checks if any merges are now necessary and returns a `MergePolicy.MergeSpecification` if so.
`protected boolean` `LogMergePolicy.isMerged(SegmentInfos infos, int maxNumSegments, Map<SegmentInfoPerCommit,Boolean> segmentsToMerge)` Returns true if the number of segments eligible for merging is less than or equal to the specified `maxNumSegments`.
