Solr alternates returning different versions of the same document

Question

I have the following problem with Solr 4.5.1, with a cloud install with 4 shards:

I have updated a document via the Solr console (select a core, then select "Documents"). I used the CSV format to upload the document, including the document ID.

When I query the document id from the Solr console (simple query: id:"the-id-of-the-doc-I-updated"), I alternatively obtain the old document (with the values before update, and a given version number), or the new document (with the values after update, and a different version).

No log messages in the Solr console.

Any idea what might be going on, and how to fix that problem?

Thanks in advance,

Yann

This seems to be due in a bug in Solr; the Solr console doesn't handle document routing properly. Deleting documents (via a delete query), and then adding documents from the console fixed that problem.
