# Factory Reset

> Perform factory reset operations and Solr index reset for troubleshooting.

***Spectra Analyze > Administration > Configuration & Update > Factory Reset***

Performing the factory reset reverts the appliance to its default state and deletes the appliance database data, including YARA rules saved to the disk.

Users must input their password and check the confirmation box before performing this action to ensure it is not done by accident.

Click **Delete All Data and Settings**, and confirm the deletion to remove the following:

- All samples
- All YARA rulesets except Spectra Core rulesets
- All user accounts created on the appliance
- All alerts collected on the appliance
- Custom configuration values modified by the appliance users

## Solr Index Reset

**Warning: This option should be used for troubleshooting only when instructed by [ReversingLabs Support](mailto:support@reversinglabs.com).**


The Advanced Search feature uses Solr to index the samples on the appliance and their metadata in order to include them in the search results.

Administrators can use **Solr Index Reset** to manually trigger reindexing data for the search engine. Selecting and confirming this option removes the existing data from the search database and starts importing new data into it.

Reindexing the database can be helpful to resolve potential issues with advanced search when restoring the appliance database from backups. However, the reindexing process can take a long time depending on the amount of samples on the appliance. Until reindexing is complete, search results may not be accurate.
