This article describes a situation where no searchable data appears in Liferay DXP 7.0, as if the indexes disappeared and reindexing does not resolve this. It is possible that your indexes have been set to read-only.
Resolution
- Navigate to Control Panel > Configuration > System Settings > Foundation > index-status-manager-configuration-name
- Uncheck the Index read only box.
- Click the Update button.
After performing these steps, you will need to reindex users from the Control Panel.
- Navigate to Control Panel > Server Administration
- Under Index Actions, click on Redindex all search indexes
This time, the reindex should complete successfully, and you should see all of your users on the Users and Organizations page.
If you still do not see your users, it may be necessary to shut down the portal, delete the /elasticsearch directory in your liferay.home, restart the portal and rerun the reindex.
