how to stop a stream?

```
dbl = LevelQuery(dbl)
dbl.query.use(full_text_engine())

stream = dbl.query( key, value )
stream.on( "data", function() { console.log( "at some point i got enough" )} );
```

At this point, how to "stop" the stream?

i tried stream.pause(), stream.close(), stream.end(), stream.stop() but none seems to work.
