-Indices level stats provide statistics on different operations happening

-(though most stats can also be retrieved using node level scope).

+
+Use the index stats API to get high-level aggregation and statistics for an index.
+
+By default,
+the returned statistics are index-level
+with `primaries` and `total` aggregations.
+`primaries` are the values for only the primary shards. 
+`total` are the accumulated values for both primary and replica shards.
+
+To get shard-level statistics,
+set the `level` parameter to `shards`.
+
+[NOTE]
+====
+When moving to another node,
+the shard-level statistics for a shard are cleared.
+Although the shard
+is no longer part of the node,
+that node retains any node-level statistics
+to which the shard contributed.
