+## Sorting

+Sorting is not supported for any of the `range` field types. Attempting to sort by a field of type range_field will result in a `400 Bad Request` response.
+For example, executing a sort query on a field of type `integer_range`,
+```console
+PUT idx
+{
+  "mappings": {
+    "properties": {
+      "my_range": {
