As of now, we don't support having an array of filters on an object -- https://github.com/camicroscope/Caracal/blob/master/handlers/filterFunction.js
You could add support for this if you want. (presumably we'd allow if the user filter array and the object filter array have anything in common?)

@birm sorry, I didn't notice that earlier. But, I have added support for an array of filters in #camicroscope/Caracal/pull/28
