Introduction

Configuration for the EPiServer FTS Service is found in the “EPiServer.Search.IndexingService” section in the web.config and is accessible via properties on EPiServer.Search.IndexingService.IndexingServiceSettings. Most of the values have defaults and are not required. Below are tables for section and element names and their defaults.
