Apply JSONPath filter to field with space

Question

I'm trying to use JSONPath ( https://github.com/jayway/JsonPath ) to search a document which has spaces in the field names:

{
  "model": {
    "Details": {
      "Nospace": "New today",
      "Random nonsense": "New today"
    }
  }
}

I'm testing using the evaluator at http://jsonpath.herokuapp.com/

This works:

$.model.Details[?(@.Nospace== 'New today')]

But this does not:

$.model.Details[?(@.'Random nonsense'== 'New today')]

This does but is missing the filter expression:

$.model.Details['Random nonsense']

So it seems it's possible to refer to fields with spaces, but I haven't found how to use them in a filter. Is it possible? I have tried many other combinations with no luck, and don't seem to find anything online about it either.

Thanks.
