Two documents with same ID but different hash

Hello,

I sent some data into the solr/lucene index but when I query
the data I see weird results.

There are documents with identical id fields but they have different 
hash values.
Apart from the hash values the results are the same.

I thought it was impossible to have documents with same uniqueKey in the 
index?
Evidently this is not the case? Could the index be corrupt somehow?

from schema.xml:
<uniqueKey>id</uniqueKey>


Best regards,
Lauri Hyttinen

Hello again,

Well after further review the ID's are different. The difference was 
just so small I missed it after staring it for a few hours.

BR,
Lauri

I have no idea what you mean by "different hash", and you
haven't provided much information go on here.

What is your evidence that the document is in the index
twice? If you're inspecting the index at a low level
that's expected, since documents are just marked
as deleted not immediately removed from the index.

Are you using shards? If so, is it possible that you've indexed
documents with the same ID to different shards?

Best
