   @tomasged If I've understood the problem correctly, I think you can use `/db/_changes?descending=true&since=[firstdocseq]&limit=2` to get a potential previous sequence to use in replications, then you would need to verify that you've been given at least the documents you want or re-replicate and make sure your code can live with any additional documents from different order responses..
   
   A different approach might be to rely on a view and an application layer source of order (i.e. timestamp fields?)
