How can I query double nested objects in Hyperledger Fabric?

I'm using CouchDb in Fabric and I have the next JSON document

{

"id": "invoice1",

"sellers": [{

"names": "Clark",

"items": [{

"iditem": "item1",

"properties": [{

"width": "212cm"

}]

}]

}]

}

How can I query the width property?
