Use the Advanced settings page to modify settings that govern OpenSearch Dashboards behavior. These settings can be used to customize the look and feel of the application, change the behavior of certain features, and more. A view of the interface is shown in the following image.
To access Advanced settings, go to Dashboards Management and select Advanced settings. The page is divided into the following sections: General, Appearance, Discover, Notifications, Search, Timeline, and Visualization. Each section contains a set of its respective settings. You can modify these settings by editing their fields. Once you've made the changes, select Save to apply them.
{::nomarkdown}
{:/} Note
Certain settings require you to modify the opensearch_dashboards.yml file and restart OpenSearch Dashboards.

| Setting | Description |
|---|---|
courier:batchSearches |
Enables or disables how dashboard panels load. When disabled, panels load individually, and search requests end when the user navigates away or updates the query. When enabled, all panels load together when all data is loaded, and searches do not end. Default is Off. |
courier:customRequestPreference |
Specifies whether to use the request preference with the custom setting. Default is _local. |
courier:ignoreFilterIfFieldNotInIndex |
Enables or disables support for dashboards that contain visualizations using different indexes. When disabled, all filters are applied to all visualizations. When enabled, visualization filters are ignored if the visualization's index does not contain the field being filtered. Default is Off. |
courier:maxConcurrentShardRequests |
Defines the maximum number of concurrent shard requests that OpenSearch Dashboards can initiate for _msearch requests. Set to 0 to disable the setting and to use the default value set by OpenSearch. Default is 0. |
courier:setRequestPreference |
Defines which shards handle your search requests. Options include Session ID, Custom, and None. Session ID restricts operations so that all search requests run on the same shard and reuses shard caches across requests, which can improve performance. Custom is used to define your own preference. Use courier:customRequestPreference to customize your preference value. None means that no preference is set. This option can provide better performance because requests can be spread across all shard copies. However, results might be inconsistent because different shards might be in different refresh states. Default is Session ID. |
search:includeFrozen |
Specifies whether to include frozen indexes in search results. If enabled, frozen indexes are included in search results. Searching through frozen indexes can increase the search time. Default is Off. |
The following table describes the Timeline settings.
