GET method and Query String

[Jim Alateras]

I am interested in hearing how people use the query string to
constrain a GET.
For instance if i want to get a list of cars registered between
03/2000 and 09/2006

/cars?registeredDate$from=03-2000&registeredDate$to=09-2006
/cars?registeredDate!from=03-2000&registeredDate!to=09-2006
/cars?registeredDate=[03-2000,06-2006]

How are people encoding expressions such as >, >=, < and <= within a
GET request.
