Yoni Amir created SOLR-3814:
-------------------------------
Summary: Partial document update silently breaks multi-valued
constraint
Key: SOLR-3814
URL: https://issues.apache.org/jira/browse/SOLR-3814
Project: Solr
Issue Type: Bug
Components: update
Affects Versions: 4.0-BETA
Environment: windows xp, java 6 or 7
Reporter: Yoni Amir
1) Download the tutorial, start solr, and post to it the file solr.xml as
explained in the tutorial.
2) query *:* and verify that you have one document in solr with id SOLR1000
3) copy the xml file and create a partial update command for that document. I
used something like this:
<add>
<doc>
<field name="id">SOLR1000</field>
<field name="manu" update="set">new value</field>
</doc>
</add>
4) Post this document to solr. It will succeed.
5) Query *:* again, and you will notice something strange. There is still one
document, but in the results the field price_c appears twice, even though it is
not a multi-valued field.
<result name="response" numFound="1" start="0">
<doc>
<str name="id">SOLR1000</str>
...
<float name="price">0.0</float>
<arr name="price_c">
<str>0.0,USD</str>
<str>0,USD</str>
</arr>
</doc>
</result>
6) change the value in the xml that you just sent (e.g. "new value2") and post
it again to solr. Now solr throws an exception:
SEVERE: org.apache.solr.common.SolrException: ERROR: [doc=SOLR1000] multiple
values encountered for non multiValued field price_c
: [0.0,USD, 0,USD]

I am trying to use the partial update feature in my current project, and this
is a showstopper for us right now.
Thanks,
Yoni
