I’ve created a custom WP taxonomy called vertical_taxonomy. I am trying to get Jetpack to take that into account when fetching related posts: I want only the posts that have the same vertical_taxonomy. I’ve tried to add that to Elastic Search filters, but then I get no results.

This is what my filters look like:

 array(2) { 
    [0]=> array(1) { 
        ["term"]=> array(1) { 
            ["taxonomy.vertical_category.slug"]=> string(9) "designers" 
        } 
    } 
    [1]=> array(1) { 
        ["term"]=> array(1) { 
            ["post_type"]=> string(4) "post" 
        }
    }
}
