Programmatically add refinement

[mauxtin]

I am looking for a way of adding a refinement programmatically.

My use case is the following:
When someone visits /category/category1 I get a category_id.
I want to only display the entries that have this specific category_id. (which is an attribute on my index entries of course).

So when I set my host, index and type (using this.setHost, this.setIndex and this.setType) I also want to set a refinement (e.g. this.setRefinement('category_id', category_id) ) and only display those.

How would I go for achieving that?

Seems to be duplicated of #22

FWIW The solution I came up with was this (of course after setting host port index etc. )

    this.addInstruction({
      fun: 'andFilter',
      args: ['term', 'category.id', this.category.id]
    })
