Filter v10 rest for greater than date.

I've got a request that looks like this

172.20.5.91/.../ORDER_orderentry
But I would like to add filter[2][enh_schedule_active_from_c] > 2015-07-20

Is this possible?  I realise I can't do a greater than symbol in http parameter, but is there a way around this, I couldn't find an example of this in the rest documentation.
