Documentation about new PV for system-search have been taken care by New PV "system-searchd" is missing from the documentation.

But exact procedure to take backup/restore of it is not clear yet in the document.

APIManagerBackup/APIManagerRestore by 3scale operator seems not to take it into account.

I do not know if it's intended or not. But if it's intended, I think that reindex by the following command should be performed as restore operation once restoration completes. 

$ oc exec -t dc/system-sidekiq -- bash -c "bundle exec rake searchd:optimal_index"

The request of this Jira is either of :

• take care system-searchd pv by APIManagerBackup/APIManagerRestore 
• add re-indexing instruction to the document to Restoring system-searchd section.
