+=== `_size`
+
+The `_size` field allows to automatically index the size of the original
+`_source` indexed. By default, it's disabled. In order to enable it, set
+the mapping to:
+
+[source,js]
+--------------------------------------------------
+{
+    "tweet" : {
+        "_size" : {"enabled" : true}
+    }
+}
+--------------------------------------------------
+
+In order to also store it, use:
+
+[source,js]
+--------------------------------------------------
+{
+    "tweet" : {
+        "_size" : {"enabled" : true, "store" : true }
+    }
+}
+--------------------------------------------------
