I have an urgent demo showcase for Ghost and I have the following context. Though not specific to Ghost, its a general problem
{
  posts: [{
    name: 'post1',
    id: 1,
    tags: [{
      id: 1,
      name: 'tag1'
    },{
      id: 5,
      name: 'tag5'
    }]
  },
  {
    name: 'post2',
    id: 2,
    tags: [{
      id: 1,
      name: 'tag1'
    },{
      id: 3,
      name: 'tag3'
    }]
  }]
}
I want to create a filter helper in HandleBars.js which will display all posts whose tag name is 'tag1'
Something like
{{#filter posts tags[].name="tag5"}}
   <h1> {{name}} </h1>
{{/filter}}
Outputs
<h1> post1 </h1>
EDIT
I have seen filter helpers, I think what I need is deepfilter helper.
