Answer 1

This error is probably related to a mismatch with your Solr schema.xml <fields> settings and your Article class. You should be able to debug your program and examine the Bad Request error for more details on what the issue is. Or you can examine the server logs for Solr (in your hosting container eg Jetty, Tomcat) for more details as well.

Additionally, I would change your Tags property on the Article class to be the more generic ICollection like the multiValued examples on the SolrNet Mapping wiki .
