RE: Ignoring Duplicates in Multivalue Field

[Tomer Levi]

Hi Ahmet,
When I add the RunUpdateProcessorFactory Solr didn't remove any duplications.
Any other idea?

Hi Tomer,

What happens when you add   <processor class="solr.RunUpdateProcessorFactory" 
/> to your chain?

Hi,
I’m trying to make my “update” request handler ignore multivalue duplications 
in updates.
To make my use case clear, let’s assume my index already contains a document 
like:
{
   id:”100”, 
 “myMultValueField”: [“1”,”2”,”3”]
}

Later I would like to send an update like:
{
   id:”100”,” 
   myMultValueField” {“add”:”2”}
}

How can I make the update request handler understand that “2” already exist and 
ignore it?
I tried to add update chain below but it didn’t work for me.

<updateRequestProcessorChain name="uniq-fields">
                   <processor class="solr.UniqFieldsUpdateProcessorFactory">
                                <str name="fieldRegex"> myMultValueField </str>
                  </processor>
   </updateRequestProcessorChain>

And add it to my requestHandler:
<requestHandler name="/update" class="solr.UpdateRequestHandler">       
           <lst name="defaults">
             <str name="update.chain">uniq-fields</str>
           </lst>
    </requestHandler>
