Sort options in v1.0.3

[Katsivelisp]

Hello,

I have been trying to play around with the sort options in v1.0.3. Currently there are two options supported in search.jsx
export const sortOptions = [ { field: 'modified', order: 'desc', label: 'Upload date' }, { field: 'title', order: 'asc', label: 'Alphabetical' } ];

If I change one of the two, nothing particularly happens. Even if I change the sort order, the results are still retrieved in the same order. I was wondering whether it is documented somewhere how I would be able to change/extend these options.

A follow-up question is, which field from the JSON schema does "modified" correspond to?
