<h1>List of controller properties/query params:</h1>
{{#each-in this as |key value|}}
{{#if (debug-filter value)}}
{{key}}: {{value}}<br>
{{/if}}
{{/each-in}}

<br><br>
<h1>List of selected filters:</h1>
{{#each filter_breadcrumb as |bc|}}
<a href="#" {{action "removeFilter" "filter_breadcrumb" bc}}>{{bc}}</a><br>
{{/each}}

<br><br>
<h1>available filters (click to add to selected filters list above)</h1>
<br>
{{#each aggregations.breadcrumb as |breadcrumbs|}}
<a href="#" {{action "addFilter" "filter_breadcrumb" breadcrumbs.key}}>{{breadcrumbs.key}} ({{breadcrumbs.doc_count}})</a><br>
{{/each}}
<br><br>
When the empty array assignments are made directly in the controller properties, they are recognized in the object as arrays and the
addFilter action (pushObject) works.
