My best guess, which could be wrong, is that you have documents with the
same uniqueKey in more than one shard of your collection.  With
SolrCloud, this usually happens when the router is implicit, or when
routing is overridden.  The implicit router is correctly named, but the
meaning is often misunderstood.  The best interpretation of its meaning
is "manual routing."

When this problem happens you may find that numFound sometimes changes
when running the same query more than once, even when the index hasn't
changed.  What router are you using on your collection, and are you
influencing the routing when you index?

the duplicate documents.

Side issue:  Is that a literal paste of the full response, or were there
contents inside the <doc> tags?  The XML that was pasted had plus signs
next to the <doc> tags, which might have come from those tags being
