Using Jetty9 and newest Solr Version which is included in Ubuntu 18.04
When I search for a Dataset via the MapWidget i get this Error:

Begin with the MapWidget search request and the logged /select parameters; reproduce the failure with the reported Jetty 9 and Solr versions. Trace which field or query component produces the invalid prefix-coded value, then document a verified fix or compatibility requirement and confirm the request no longer returns status 500.
