firebase - Retrieve only specific keys from collection

I would like to store an array of notes, where each note contains a title and a body. Is it possible to retrieve the list of note titles without the body?

For example:

notes: [
  ewi4ef36wi: {
    title: 'Shopping List',
    body: 'todo'
  }
  o9kng23inw: {
    title: 'Things To Do',
    body: ''
  }
]

How could I just retrieve the list of titles?
