 `index.merge.scheduler.max_thread_count`
 :   The maximum number of threads on a **single** shard that may be merging at once. Defaults to `Math.max(1, Math.min(4, <<node.processors, node.processors>> / 2))` which works well for a good solid-state-disk (SSD). If your index is on spinning platter drives instead, decrease this to 1.
+
 `indices.merge.disk.check_interval`
 :   The time interval for checking the available disk space. Defaults to `5s`.
+
 `indices.merge.disk.watermark.high`
 :   Controls the disk usage watermark, which defaults to `95%`, beyond which no merge tasks can start execution.
 The disk usage tally includes the estimated temporary disk space still required by all the currently executing merge tasks.
 Any merge task scheduled *before* the limit is reached continues execution, even if the limit is exceeded while executing
 (merge tasks are not aborted).
+
 `indices.merge.disk.watermark.high.max_headroom`
 :   Controls the max headroom for the merge disk usage watermark, in case it is specified as percentage or ratio values.
 Defaults to `100GB` when `indices.merge.disk.watermark.high` is not explicitly set.
