I think you should not use filters that way. Filters are for transforming inputs based on optional params.

The problem here would be that you're immediately returning a promise from the filter function. And that's nothing Angular can deal with as a result from a filter.

My suggestion therefore would be this - fetch the result first, work with the filter based on the result:

As you'd be bombarding your server quite a bit with requests whenever you try to filter your data.
