We are planning to store the 2 Elasticsearch cluster.
Cluster 1 will store the data using neoFs file-system. Cluster 2 will store the data using mMap file-system and will store the result of queries fired on cluster1. Later, we would search on cluster 2 to apply some more filtering/condition on fetched records.

It depends on what you want to cache. In most cases with ES, cache is overkill because ES uses internal caching, and it easily ends up in the double caching problem which affects performance.
Saving ES query results? Depends on your queries, their runtime, concurrency, length of result set, network latency...
