Cron Re-Indexing

Which file has to triggered for cron re-indexing or just an command is enough.
*/5 * * * * php -f /absolute/path/to/magento/shell/indexer.php – -reindex algolia_queue_runner


this is a line which you need to put to your crontab file. Just change the path to your actual indexer.php file.

Does Index need to be in manual update or update on save
Thanks for you reply.

Algolia Search Queue Runner…Only this index is working on cron not other indexes…

We have done exactly, what the documentation had…but still the required index doesn’t working…
