@@ -143,6 +143,8 @@ OpenSearch supports the following dynamic index-level index settings:
 
 - `index.search.idle.after` (Time unit): The amount of time a shard should wait for a search or get request until it goes idle. Default is `30s`.
 
+- `index.search.default_pipeline` (String): The name of the search pipeline that is used if no pipeline is explicitly set when searching an index. If a default pipeline is set and the pipeline doesn't exist, then the index requests fail. Use the pipeline name `_none` to specify no default search pipeline. For more information, see [Default search pipeline]({{site.url}}{{site.baseurl}}/search-plugins/search-pipelines/using-search-pipeline/#default-search-pipeline).
+
 - `index.refresh_interval` (Time unit): How often the index should refresh, which publishes its most recent changes and makes them available for searching. Can be set to `-1` to disable refreshing. Default is `1s`.
 
 - `index.max_result_window` (Integer): The maximum value of `from` + `size` for searches of the index. `from` is the starting index to search from, and `size` is the number of results to return. Default is 10000.
