Reindex data to make newly added information searchable

There are some situations where data coming in to Splunk Phantom or Splunk SOAR can't be indexed, and therefore can't be searched. You can reindex information sections to make this information searchable.

Below are some situations that require you to reindex your data:

• The embedded Splunk Enterprise or external Splunk Enterprise or Splunk Cloud Platform deployment was offline or unreachable.
• Upgrading Splunk Phantom from a version earlier than 4.0.
• Converting from a single Splunk Phantom instance to a cluster.
• Changing your search setting configuration, such as switching from using the embedded Splunk Enterprise to an external Splunk Enterprise or Splunk Cloud Platform instance.

Each section in the Section to Reindex drop-down list represents multiple database tables or information stores. For example, the Action index contains results for both action runs and app runs. The Playbook index covers both playbooks and custom lists.

To reindex your data, perform the following tasks in Splunk Phantom or Splunk SOAR:

1. From the main menu, select Administration.
2. Click Administration Settings.
3. Click Search Settings.
4. In the Reindex Search Data section, select an information section from the Section to Reindex drop-down list.
5. Click Reindex.

Reindexing is resource intensive and can impact system performance. Large data sets may take some time to reindex.
