search in nested array

[fraserxu]

I have a nested object like this:

[
  {
    name: 'levelA',
    number: 12341,
    district: [
      {
        name: 'levelB',
        number: 12341,
        township: [
          {
            name: 'levelC',
            number: 12341,
            tv: [
              {
                name: 'levelD',
                number: 12341
              }
            ]
          }
        ]
      }
    ]
  },
  {
    name: 'levelA2',
    number: 12341,
    district: [
      {
        name: 'levelB2',
        number: 12341,
        township: [
          {
            name: 'levelC2',
            number: 12341,
            tv: [
              {
                name: 'levelD2',
                number: 12341
              }
            ]
          }
        ]
      }
    ]
  }
]

I want to filter the result by name at all levels so I write the search like this:

let fuse = new Fuse(data, {
  keys: ['name']
});
fuse.search(keywords);

But this only return me the result in the first level of name. I'm not sure how to index the name in the second or deeper level because it's not an object.

Maybe something like this keys: ['name', 'district.name']?

@krisk Any ideas? Thanks.

+1 for this

something like this should work:
keys: ['name', 'district.name','district.township.name','district.township.tv.name']
