RethinkDB pagination using slice or limit & skip with changes() - pagination

Question

How can i do pagination in RethinkDB with changes()?
None of these options does not work:
r.db('bustest').table('client').orderBy({index: r.desc("id")}).slice(3, 3).changes()
r.db('bustest').table('client').orderBy({index: r.desc("id")}).skip(3).limit(3).changes()
Only it works:
r.db('bustest').table('client').orderBy({index: r.desc("id")}).limit(3).changes()
UPDATE:
For example, skip after changes():
r.db('bustest').table('client').orderBy({index: r.desc("id")}).limit(3).changes({squash: 0.05, includeInitial: true, includeStates: true})
return:
{
"state": "ready"
},
{
"new_val": {
"first_name": "Gruzin" ,
"id": "e9580339-b908-4349-a208-c3d1e25bf7ba" ,
"last_name": "Bagal"
}
},
{
"new_val": {
"first_name": "e31db5422cd74040" ,
"id": "efadedd0-56f2-498f-ad04-5191e2be1244" ,
"last_name": "27d6b3a140235275"
}
},
{
"new_val": {
"first_name": "2ba4a9d0e3616865" ,
"id": "f5c7f3b7-23d2-4661-a5b7-91b977635556" ,
"last_name": "b7f4df90a27bb05b"
}
},
{
"state": "initializing"
}
And with skip:
r.db('bustest').table('client').orderBy({index: r.desc("id")}).limit(3).changes({squash: 0.05, includeInitial: true, includeStates: true}).skip(3)
return:
{
"state": "ready"
},
{
"new_val": {
"first_name": "Gruzin" ,
"id": "e9580339-b908-4349-a208-c3d1e25bf7ba" ,
"last_name": "Bagal"
}
}
Skip after changes() didn't work. But pagination with changes() is very important part for my projects.

That's what is documented on https://rethinkdb.com/docs/changefeeds/ruby/#filtering-and-aggregation
You cannot use them with slice skip. Only orderBy, and follow by limit. Only orderBy before changes also works
To paginate the changes itself, (mean data return by change feed), after changes(), you can call skip, and just iterator the return cursor yourself. However, if you use limit or slice after changes, the changefeeds only return that amount of change, and close changefeed.
