There is a big difference between a change-stream and a realtime query. For example mongodbs cursor-stream is a good way to observe the events that happen to a specific collection or documents that match some criteria.
If you want the realtime-results of a query that has sorting, skip limit etc. than it is really hard to warp the changestream into this. In fact this is exactly what EventReduce could do for you.
For more information about the difference I recommend the video "Real-Time Databases Explained: Why Meteor, RethinkDB, Parse & Firebase Don't Scale" https://www.youtube.com/watch?v=HiQgQ88AdYo&t=1703s
