Filter on date fields for student search

[SCCarl]

Hi

I'm wondering if it's possible to filter student data on admission date/date of leaving? Looking through the docs I see I can filter on updated/created before/after a certain date but I was wondering if this was possible for specific fields and if so how would I specify if it's before or after this date.

var param = new `Dictionary<string,string>();

//how would I be able to say whether I want it > or < the date specified?
param.Add("admission_date", DateTime.Today.ToString("YYYY-MM-DD HH:mm:SS");

this.client.school.students.all(new string[] {"education_details", "registration", "extended_details"},param);

Thanks for your help
