Description

When adding a new field to the schema using schema-api, the new field is not known by the current SolrIndexSearcher. In SolrCloud any core gets reloaded after the new schema is persisted, this does not happen in case of stand alone HTTP Solr server or EmbeddedSolrServer.

So currently an additional commit is necessary to open a new SolrIndexSearcher using the new schema.

Fix is really easy: Just reload the core!
