+==== ccs based reindex from remote
+
+Reindex supports Cross-cluster search (<<modules-cross-cluster-search,{ccs}>>) based reindexing from a remote Elasticsearch cluster:
+
+[source,console]
+--------------------------------------------------
+POST _reindex
+{
+  "source": {
+    "index": "cluster_one:my-index-000001"
+  },
+  "dest": {
+    "index": "my-new-index-000001"
+  }
+}
+--------------------------------------------------
+// TEST[setup:my_index_big]
+
+The `index` parameter must be specified with the remote cluster name and the index name, separated by 
+a colon (e.g., cluster_one:my-index-000001).
+
+NOTE: Reindexing requires that the remote cluster be configured on the local cluster.
