Do those documents have the same value in the uniqueKey field? It must be an exact match -- a deviation in upper/lower case will be treated as a new document. If they do have identical information in the uniqueKey field, then there are a few possible problems: Are you indexing full documents, or are you doing Atomic Updates? An atomic update is by definition a change, not a replacement ... so unless that change includes deleting fields, they would not be affected. https://wiki.apache.org/solr/Atomic_Updates If your collection has multiple shards, then this paragraph may apply: What is the router set to on the collection? If it is "implicit" then you may have indexed the new document to a different shard, which means that it is now in your index more than once, and which one gets returned may not be predictable. The same thing may be true if you are using composite routing and including information in the key that sends the document to a different shard from where it was originally indexed. Thanks, Shawn
