hi all.

My ES cluster(5 nodes working) is now under memory pressure, full gc stop-the-world. so I have to do some tuning.  
every document in ES are not analyzed and doc\_values are enabled.

all of the search request called through kibana 4.  
I know time ranged queries could be cached but usually can't be hit, because now timestamp moves.

in that case can I turn the cache off?  
some modification like this..

indices.fielddata.cache.size: 30%  
indices.cache.filter.size: 10%  
indices.cache.query.size: 10%  
--\>  
indices.fielddata.cache.size: 1%  
indices.cache.filter.size: 1%  
indices.cache.query.size: 1%

ES reference doc says doc\_values give a big advantage with memory pressure.  
So I wonder why there are so much fielddata cache and fielddata eviction even I enabled doc\_values to all data.

summary.

1. fielddata cache needed even all doc\_values enabled?
2. kibana may cant hit the filter cache, query cache. turn cache 0% will help?
3. any cache configure suggestion for large ES+ many kibana query.

Thanks.
