| Stored      | <p><strong>Optional</strong>. If <strong>stored=true</strong>, the actual value of the field can be retrieved by queries (to tell Solr to store the original text in the index somewhere).<br><br>If <strong>stored=false</strong> will make the field only indexed and can’t be retrieved in output.</p> |
| Multivalued | **Optional**. If true, indicates that a single document might contain multiple values for this field type.                                                                                                                                                                                                |

For example :

* If **stored=true** and **indexed=false**: field isn’t searched, but need to be displayed in the search results.
* If **stored=true** and **indexed=true**: field should be searchable and displayed in the search results.
