## Remarks

**For M-Files components only.** Search indexers call it to learn which properties to index per
object type. Applications should use [GetObjectTypes](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectTypes/GetObjectTypes/index.md)
and [GetPropertyDefs](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCPropertyDefs/GetPropertyDefs/index.md).
- Requires the system administrator server role (server right `log_in_to_any_vault`).
