# Configure the query rate limit
In Coveo for Sitecore, a query rate limit is set to mitigate the outgoing communication to the Coveo index.
While the default settings fit the needs of most installations, you might want to customize them further.

To configure these settings

. Open the `<SITECORE_INSTANCE_ROOT>\App_Config\Include\Coveo\Coveo.SearchProvider.Rest.Custom.config` file in a text editor.

. In the `sitecore\coveo\restEndpointConfiguration` node, add/edit the following parameters:
