The new `exists` style filtering is not supported by `addPreSearch` within a model driven app. Please can it be added.

See here for more detail on my attempts to make it work

Hey @filcole. Thanks for the thorough documentation on this. I'd suggest raising a support request with Microsoft as it feels like a bug in the client side APIs. As you right state, the query appears to be running fine at the platform level
