Solr: can not sort on multivalued field #4

Open cyplas opened 7 years ago

We frequently get "can not sort on multivalued field" in the solr logs:

Not sure what causes this or how it affects the user.

Lindat says this is probably due to some structure changes, and that a closer look at the apache logs and using a remote debugger could help.
