Configure Field Mapping

While creating/updating an indexer, user can easily configure (create, update or delete) field mapping for an indexer that essentially creates a mapping between data source fields and index attributes. If AI enrichment capability is enabled, it is possible to easily configure output field mapping between a skillset output and index attributes.
Cerebrata also enables user to specify and configure mapping functions. Cerebrata supports "Base64 Decode", "Base64 Encode", "extractTokenAtPosition", and "jsonArrayToStringCOllection" mapping functions.
