Is there an easy way to index tables? or is it like a regular Solr server where I still need to create my cores and configurations?
Martini Runtime has a couple of one-liners that converts a Gloop Model to a Solr schema and vice versa. So if you have an existing Gloop Model you can convert it into a Solr schema, or If you have an existing Solr schema, you can convert it into a Gloop Model.
Once you have a Gloop Model, Martini includes a bunch of Solr services you can use to easily index your Solr documents. The Examples Package has an example that demonstrate indexing a Solr document to a custom Solr search index. You still need to have your Solr cores and configurations, but the one-liners will make it easy for you to index your custom indices.
