+|======
+| Name               | Required  | Default | Description
+| `field`            | yes       | -       | Field containing the URI string.
+| `target_field`     | no        | `url`   | Output field for the URI object.
+| `keep_original`    | no        | true    | If `true`, the processor copies the
+unparsed URI to `<target_field>.original`.
+| `remove_if_successful` | no    | false   | If `true`, the processor removes
+the `field` after parsing the URI string. If parsing fails, the processor does not
+remove the `field`.

+Here is an example definition of the URI parts processor:
+
+[source,js]
+--------------------------------------------------
+{
+  "description" : "...",
+  "processors" : [
+    {
+      "uri_parts": {
+        "field": "input_field",
+        "target_field": "url",
+        "keep_original": true,
+        "remove_if_successful": false
+      }
+    }
+  ]
+}
+--------------------------------------------------
+// NOTCONSOLE
+
+When the above processor executes on the following document:
+
+[source,js]
+--------------------------------------------------
+{
+  "_source": {
+    "input_field": "http://myusername:mypassword@www.example.com:80/foo.gif?key1=val1&key2=val2#fragment"
+  }
+}
+--------------------------------------------------
+// NOTCONSOLE
+
+It produces this result:
+
+[source,js]
+--------------------------------------------------
+"_source" : {
+  "input_field" : "http://myusername:mypassword@www.example.com:80/foo.gif?key1=val1&key2=val2#fragment",
+  "url" : {
+    "path" : "/foo.gif",
+    "fragment" : "fragment",
+    "extension" : "gif",
+    "password" : "mypassword",
+    "original" : "http://myusername:mypassword@www.example.com:80/foo.gif?key1=val1&key2=val2#fragment",
+    "scheme" : "http",
+    "port" : 80,
+    "user_info" : "myusername:mypassword",
+    "domain" : "www.example.com",
+    "query" : "key1=val1&key2=val2",
+    "username" : "myusername"
+  }
+}
+--------------------------------------------------
+// NOTCONSOLE
