+
+If there is already a `bar` field nested under `foo` then
+this processor merges the `foo.bar` field into it. If the field is
+a scalar value then it will turn that field into an array field.
+
+For example, the following document:
+
+[source,js]
+--------------------------------------------------
+{
+  "foo.bar" : "value2",
+  "foo" : {
+    "bar" : "value1"
+  }
+}

+[source,js]
+--------------------------------------------------
+{
+  "foo" : {
+    "bar" : ["value1", "value2"]
+  }
+}
+--------------------------------------------------
+// NOTCONSOLE
+
+If any field outside of the leaf field conflicts with a pre-existing field of the same name,
+then that field needs to be renamed first.
+
+Consider the following document:
+
+[source,js]
+--------------------------------------------------
+{
+  "foo": "value1",
+  "foo.bar": "value2"
+}
+--------------------------------------------------
+// NOTCONSOLE
+
+Then the `foo` needs to be renamed first before the `dot_expander`
+processor is applied. So in order for the `foo.bar` field to properly
+be expanded into the `bar` field under the `foo` field the following
+pipeline should be used:
+
+[source,js]
+--------------------------------------------------
+{
+  "processors" : [
+    {
+      "rename" : {
+        "field" : "foo",

+    {
+      "dot_expander": {
+        "field": "foo.bar"
+      }
+    }
+  ]
+}
+--------------------------------------------------
+// NOTCONSOLE
+
+The reason for this is that Ingest doesn't know how to automatically cast
+a scalar field to an object field.
