Thanks. But this yields an error in FacetModule:
java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Map
at
org.apache.solr.search.facet.FacetModule.prepare(FacetModule.java:100)
at
org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:247)
at
org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:156)
at org.apache.solr.core.SolrCore.execute(SolrCore.java:2073)
...
Is it supposed to work? I also found open issues SOLR-6348 and SOLR-6352 which
made me doubt is wat supported at all.
Thanks,
Markus
