Configure full-text search client

Describes how to set up full-text search client.

📘

Note

The Full-text Search Service applies to Optimizely Content Management System (CMS 11) and is not supported on Optimizely Digital Experience Platform (DXP) and other cloud service deployments. It is a legacy feature that will be removed in future versions.
This section is not supported for ASP.NET Core-based applications.

The Optimizely full-text search client (FTS Client) configuration is in the EPiServer.Search section of web.config and is accessible through the EPiServer.Search.SearchSettings.Config property. Most of the values have defaults and are not required. The following tables show section and element names and their defaults.
