Feature Request: Nested Filter in Expand

[ozum]

Hi,

Is it possible to support Nested Filter in Expand?

Example taken from http://www.odata.org/getting-started/basic-tutorial/#expand

GET serviceRoot/People?$expand=Trips($filter=Name eq 'Trip in US')

I got:

SyntaxError: Expected "&", ",", ".", "/" or [a-zA-Z0-9\-_] but "(" found.

Thank you,
