As mentioned on CouchDB documentation:

... the emit() function can be called multiple times in the map function to create multiple entries in the view results from a single document...

Now we are going to use emit() multiple times in the map function. Also we are going to emit arrays to have both invoiceNumber and barCode as the index, like this:

var myIndex = {
    _id: '_design/my_index',
    views: {
        'my_index': {
            map: function (doc) {
                for(var i=0, length=doc.invoices.length; i

Now lets PUT our above design document and query it with PouchDB:

pouch.put(myIndex).then(() => {
  // query the index
  return pouch.query('my_index', {key: ['12312313','1234324']});
}).then(result => {
  // found docs with invoiceNumber === '12312313' and barCode === '1234324'
  console.log('Result: ', result)
});
