With ES on a single machine, "tuning" does not cure the symptoms in the long run. ES was designed to scale out on many nodes, so the simplest path is to add nodes.
In a restricted environment, you could try to disable features that consume a fairly amount of resources: disable _source and _all field, bloom codec filter cache, reduce complex analyzers in the mapping, reduce number of shards, reduce filter caches ...
