Hi All,

Using Elasticsearch 6.3.0, I'm trying to understand the meaning of the following (from /\_nodes/stats):

query\_cache: {  
memory\_size\_in\_bytes: 38247165,  
total\_count: 11278236,  
hit\_count: 1672112,  
miss\_count: 9606124,  
cache\_size: 1494,  
cache\_count: 418838,  
evictions: 417344,  
}

looks like (current?) memory size is ~38mb.  
The (total?) cache\_size is 1494mb(?) - I assume that it's in mb since the total memory size is 15gb and 10% is the default for query cache size, right?  
Anyway, I don't understand how do I have 9.6M miss if the memory\_size is so low.  
can someone explain what's going on here please?
