I’m using the Solr module and I noticed that it is unable to index non DC fields (for example fields from another metadata schema like FOAF) and DC fields filled out by custom vocabulary.
I added the fields in the mapping but they didn’t appear on the Solr server.
Is there a way to index such fields and how ?
The elements of the Dublin Core are enabled by default, but you have to set the other fields you want in Solr > Nodes > Mapping (3rd action) > Items > Edit > Add the fields you want.
I set the other fields following your advice and it works but if the field (DC or non DC) is filled out by custom vocabulary, it doesn’t.
This is fixed in https://github.com/omeka/omeka-s/pull/1262, but not integrated upstream.
