About fielddata cache and filter cache expire

My Cluster Specification
node : 7
Memory : 24G
JVM : 12G, OS : 12G

elasticsearch version : 1.1.1

set elasticsearch.yml
indices.cache.filter.size: 30%
indices.fielddata.cache.size: 50%

I saw the head plug-in.
cache was about fitler cache and fielddata cache 200mb.
all cache expires after about 10 minutes.
I have enough memory.

What options do I need?
