Having Issues adding new Facets.

[mkjmckinlay]

I'm trying to update my Oscar store to user this instead of Haystack.

On my site I have:

OSCAR_SEARCH_FACETS = {
"fields": OrderedDict(
[
("category", {"name": "Category",
"field": "category",
'options': {
'order': {"_term": "asc"}
},
}),
("brand", {"name": "Brand",
"field": "brand",
'options': {
'order': {"_term": "asc"}
},
}),

    ],
),
'queries': OrderedDict(),

}

Cant seem to work out how I should be doing this within the new set up?
