As a follow-up question to this article: [https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-search-speed.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-search-speed.html) I would like to know which way to best improve search time for my ES database.

Would it be:

1. To increase RAM or
2. To add more nodes?

I currently have a 4 gb RAM one node setup.
