> I'm using filtered replication to maitain a database that has a subset of the documents of some other database.
> The problem I have is when I change the filter. If the filter allows for more documents to be replicated, those that
> were created before the last replication are not replicated. So, I have to remove the database and recreate it.
> I see two solutions that can be implemented to help in this situation. The first one is for the filtered replication
> to restart whenever the filter changes (maybe also adding an argument to replicate to tell that" we want this to happen).
> Another solution is to add an argument to replicate ("start_seq", as sugested by fdmanana on IRC) that would be the 
> source database ""local_seq that we want the replication to start from. This an be set to 1 to restart from first change.
