class	LogDocMergePolicy This is a LogMergePolicy that measures size of a segment as the number of documents (not taking deletions into account).
class	LogMergePolicy This class implements a MergePolicy that tries to merge segments into levels of exponentially increasing size, where each level has fewer segments than the value of the merge factor.

class	TieredMergePolicy Merges segments of approximately equal size, subject to an allowed number of segments per tier.
class	UpgradeIndexMergePolicy This MergePolicy is used for upgrading all existing segments of an index when calling IndexWriter.forceMerge(int).
