Filter parameters

Hi,

I have a question regarding filter parameters.Can't we filter based on non-key parameters ?

say i have Cid as a key parameter and Name as property in my entity, cant i filter entries based on 'Name' property ?

DetailsSet?$filter=Cid eq 'C#######'

is working

DetailsSet?$filter=Name eq 'manvitha'

doesnt seem to work.

Could you please help.

Thanks,

Regards,

Manvitha
