Hi,  
I would like to get some opinions about our query cache. Bellow is our query cache stats:  
"query\_cache": {  
"memory\_size\_in\_bytes": 29537552,  
"total\_count": 144333168499,  
"hit\_count": 11702200196,  
"miss\_count": 132630968303,  
"cache\_size": 2557,  
"cache\_count": 1313500,  
"evictions": 1310943  
}

\what do you think by looking at the numbers? My first reaction was cache size was too small. I have the following in elasticsearch.yml:  
indicies.queries.cache.size: 20%

Heapsize 8 GB, total physical memory on the box is 16 GB.

thanks
