[Koha] Koha cron job - Elasticsearch index updates

[C P Hong]

Hello

I am testing Elasticsearch in Koha 18.11.

Is there a configuration in Koha to run cron job for Elasticsearch?

I ask this question because I cannot find records of books by searching the
catalog that I had cataloged recently into Koha.

Similar to the above question.

>From wiki -https://wiki.koha-community.org/wiki/Elasticsearch#Configuration

do I need to run this command regularly for records that I entered into
Koha?

 misc/search_tools/rebuild_elastic_search.pl -v -d

Please let me know.

Best Regards
Chee
