Hello,

I want to copy all data from a multivalued field joined together in a single
valued field.

Is there any opportunity to do this by using solr-standards?

kind regards

There is not currently, but it certainly makes sense.

Anyone know of an open issue for this yet?  If not, we should create one!

Part of it has just recently been commited to trunk actually...

https://issues.apache.org/jira/browse/SOLR-2802

https://builds.apache.org/job/Solr-trunk/javadoc/org/apache/solr/update/processor/ConcatFieldUpdateProcessorFactory.html

...with that, it's easy to say "anytime multiple values are found for a
single valued string field, join them together with a comma".

the only piece that's missing is to "copy" from a source field in an
(earlier) UpdateProcessor.  

Theres a patch for this in SOLR-2599 but i haven't had a chance to look at
it yet.
