Assuming that you are not indexing new documents between requests, there are two reasons for this problem: 1) You have documents with the same uniqueKey value in more than one of your shards. This typically happens when the router on the collection is set to "implicit" ... which basically means "manual." 2) Your two replicas are out of sync, which might have any number of causes. Side note: "q=id:*" is a very inefficient query. You would be better off with a range query -- "q=id:[* TO *]". That would be faster and use less memory. If the id field is your uniqueKey, then an even faster query and 100% equivalent query is the one for all docs -- "q=*:*". Thanks, Shawn
