Getting Accounts with API using search doesn't have subforms.

Getting Accounts with API using search doesn't have subforms.

Hi,
If I fetch an Account(s) without using the 'search' feature of the API I get back the account with it's subform. But, when I use the search feature, the subform data is not the subform object, just an integer.

Is there a way of pulling the subforms as well when using the search function?
