No. I have say 'm' number of servers, and I need 'n' rows. To get the results, you need to run the query against all the 'm' servers, which will return 'm x n' results, then you have to re-sort it and drop the 'm x n - n' rows and return only the 'n'. So this is like retrieving the 'n' rows amongst ALL the servers, that satisfy your search criteria.

Once you retrieve the data, you will know which server each row belongs to, and you can do the writes yourself at the higher level.

Thanks.
