multiple values for a key

I'm not sure if i'm thinking of this the wrong way, so please correct me if i'm missing any assumptions

I'm trying to create a secondary index and then look up all values by that key -- maybe multiple rows have that field and i want to see them all.

e.g.

``` js
db.put(1337, {'author'; 'karissa', 'title': 'power rangers'})
db.put(1338, {'author'; 'karissa', 'title': 'power rangers 2'})

... level sec ...

index.byAuthor.get('karissa')
// returns values ==>
[
{'author'; 'karissa', 'title': 'power rangers 2'},
{'author'; 'karissa', 'title': 'power rangers'}
]
```

Is this possible in level-sec, or something else?
