+  The configuration settings for the dataset parser, a JSON object containing the following attributes:
   - `"chunk_token_count"`: Defaults to `128`.
   - `"layout_recognize"`: Defaults to `true`.
   - `"delimiter"`: Defaults to `"\n!?。；！？"`.
 
 - `dataset_id`: (*Path parameter*)  
   The ID of the dataset to update.
-- `"name"`: `string`

 #### Request parameters
 
-- `page`: (*Path parameter*)  
+- `page`: (*Filter parameter*)  
   Specifies the page on which the datasets will be displayed. Defaults to `1`.
-- `page_size`: (*Path parameter*)  
+- `page_size`: (*Filter parameter*)  
   The number of datasets on each page. Defaults to `1024`.
-- `orderby`: (*Path parameter*)  
+- `orderby`: (*Filter parameter*)  
   The field by which datasets should be sorted. Available options:
   - `create_time` (default)
   - `update_time`
-- `desc`: (*Path parameter*)  
+- `desc`: (*Filter parameter*)  
   Indicates whether the retrieved datasets should be sorted in descending order. Defaults to `true`.
-- `name`: (*Path parameter*)  
+- `name`: (*Filter parameter*)  
   The name of the dataset to retrieve.
-- `id`: (*Path parameter*)
