> How do you suggests to serialize this object?
Like a normal binary object. This scenario already exists for ScanQuery and
ContinuousQuery filters.
- It works for Java and .NET; potentially for other platforms
- Corresponding types should exist on server nodes
E.g. if a Java class `MyFilter { String containsText }` is loaded on server
nodes,
a Python thin client can easily write a corresponding BinaryObject with one
field to achieve server-side filtering.

Thanks, forgot to mention this - updated the IEP.
