    Modifier and Type | Method and Description
    --- | ---
    `TieredMergePolicy` | TieredMergePolicy.`setFloorSegmentMB(double v)` Segments smaller than this are "rounded up" to this size, ie treated as equal (floor) size for merge selection.
    `TieredMergePolicy` | TieredMergePolicy.`setForceMergeDeletesPctAllowed(double v)` When forceMergeDeletes is called, we only merge away a segment if its delete percentage is over this threshold.
    `TieredMergePolicy` | TieredMergePolicy.`setMaxCFSSegmentSizeMB(double v)` If a merged segment will be more than this value, leave the segment as non-compound file even if compound file is enabled.
    `TieredMergePolicy` | TieredMergePolicy.`setMaxMergeAtOnce(int v)` Maximum number of segments to be merged at a time during "normal" merging.
    `TieredMergePolicy` | TieredMergePolicy.`setMaxMergeAtOnceExplicit(int v)` Maximum number of segments to be merged at a time, during forceMerge or forceMergeDeletes.
    `TieredMergePolicy` | TieredMergePolicy.`setMaxMergedSegmentMB(double v)` Maximum sized segment to produce during normal merging.
    `TieredMergePolicy` | TieredMergePolicy.`setNoCFSRatio(double noCFSRatio)` If a merged segment will be more than this percentage of the total size of the index, leave the segment as non-compound file even if compound file is enabled.
    `TieredMergePolicy` | TieredMergePolicy.`setReclaimDeletesWeight(double v)` Controls how aggressively merges that reclaim more deletions are favored.
    `TieredMergePolicy` | TieredMergePolicy.`setSegmentsPerTier(double v)` Sets the allowed number of segments per tier.
    `TieredMergePolicy` | TieredMergePolicy.`setUseCompoundFile(boolean useCompoundFile)` Sets whether compound file format should be used for newly flushed and newly merged segments.
