Schema is not updated

[rkmax]

This is the first time I use Solr and bundle, follow the guide and everything seems properly but when creating an entity, I get an error

org.apache.solr.common.SolrException: ERROR: [doc=1] unknown field 'document_name_s'

I understand Solr needs a schema that can be updated dynamically. and the bundle does for me when going to store Entity into the index but this is not happening.

My entity class

/** 
 * @ORM\Entity
 * @ORM\Table()
 * @Solr\Document 
 */
class Entity {
    /** orm suff...
     *  @Solr\Id
     *  @ORM\Id
     *  @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id

    /**
     * @ORM\Column(name="product_name", type="string")
     * @Solr\Field(type="string")
     */
    private $productName;

    //...
}

Solr/lucene provides "dynamic fields" , and it looks like as if these definitions are missing. Please check your schema.xml for those definitions. You can find an example under the section "dynamic fields": http://wiki.apache.org/solr/SchemaXml

Which solr-version do you use?

solr 4.5.1 on ArchLinux. @floriansemm thanks i've created a new core with this fields
