javascript - Listen change feed of complex queries in RethinkDB -

when have query this:

r.db('universe')   .table('star')   .getall(     r.db('universe').table('ship').get(idship)('idcurrentgalaxy'),     {index: 'idgalaxy'}   )   .changes({includeinitial: true}) 

i expect update changefeed when

1. a selected star gets updated
2. the selected ship.idcurrentgalaxy changes

with query, 1. true. if possible, how can change query make 2. true?

the data behind query this:

//stars {id: 1, idgalaxy: 1, name: 'aldhafera'} {id: 2, idgalaxy: 1, name: 'duhr'} {id: 3, idgalaxy: 2, name: 'menchib'}  //galaxies {id: 1, name: 'milky way'} {id: 2, name: 'andromeda'}  //ships {id: 1, idcurrentgalaxy: 1} 

and query above result this:

{id: 1, idgalaxy: 1, name: 'aldhafera'} {id: 2, idgalaxy: 1, name: 'duhr'} 

there's no way in rethinkdb; have open 2 changefeeds , stitch them yourself. support added; can track progress @ https://github.com/rethinkdb/rethinkdb/issues/3997 .
