Is there a way to have a kind of "casting" for copyField?
I have author names in multiValued string field and need a sorting on it, but sort on field is only for multiValued=false. I'm trying to get multiValued content from one field to a non-multiValued text or string field for sorting. And this, if possible, during loading with copyField. Or any other solution? I need this solution due to patch SOLR-2339, which is now more strict. May be anyone else also. Regards, Bernd
