+        The shrink index API allows you to shrink an existing index into a new
+        index with fewer primary shards. The number of primary shards in the
+        target index must be a factor of the shards in the source index. For
+        example an index with 8 primary shards can be shrunk into 4, 2 or 1
+        primary shards or an index with 15 primary shards can be shrunk into 5,
+        3 or 1. If the number of shards in the index is a prime number it can
+        only be shrunk into a single primary shard. Before shrinking, a
+        (primary or replica) copy of every shard in the index must be present
+        on the same node.
