Hi,

my elastic search all caches are empty.Based on the elastic search documentation Node Query Cache,Shard request Cache, Field data Cache value should present when we are search operation but all value are zero.I used this url _ **\_nodes/stats/indices/query\_cache,fielddata,request\_cache** _  
and taken below reading:  
**"indices": {**  
**"query\_cache": {**  
**"memory\_size\_in\_bytes": 0,**  
**"total\_count": 0,**  
**"hit\_count": 0,**  
**"miss\_count": 0,**  
**"cache\_size": 0,**  
**"cache\_count": 0,**  
**"evictions": 0},**  
**"fielddata": {**  
**"memory\_size\_in\_bytes": 0,**  
**"evictions": 0},**  
**"request\_cache": {**  
**"memory\_size\_in\_bytes": 0,**  
**"evictions": 0,**  
**"hit\_count": 0,**  
**"miss\_count": 0}**  
**}**

In elasticsearch.yml configured below values :  
**indices.fielddata.cache.size: 10%**  
**indices.queries.cache.size: 20%**  
**indices.requests.cache.size: 10%**

This is my Search Query :  
**{"\_source" :false,"query":{"match":{"1":"Hello\_\_www200"}}}**

ElasticSearch Details :  
version : 6.0.0  
heap size : 4GB  
RAM : 32 GB  
Client : Low level rest client
