Subject Re: an "array" liked string is treated as multivalued when adding doc to solr
Date Wed, 18 Dec 2013 09:14:26 GMT
Hi Alexandre

It's quite a rare case, just one out of tens of thousands.

I'm planning to have every multilingual field as multivalued and just get
the first one while formatting the response to our business object.

The first value update processor seems a lot helpful, thank you.

All the best

Liu Bo
