6 min

📘 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 Content Management System (CMS) full-text search service (FTS Service) configuration is in the EPiServer.Search.IndexingService section of web.config and is accessible through properties on EPiServer.Search.IndexingService.IndexingServiceSettings. Most of the values have defaults and are not required. The following tables show section and element names and their defaults.
