What is the hardware requirement for the search server?

Hi, 

I am gone through the setup document for the bitbucket clustering setup(https://confluence.atlassian.com/bitbucketserver/set-up-a-bitbucket-data-center-cluster-996641208.html). There I need some clarity on the search server required hardware configuration. Thanks in advance. 

Regards,
