Hello, I am applying rollover for my cluster, also refresh\_interval = 7d for old rollover index  
But sometimes the cache/or indice is refreshed, I do not know the reason  
Do you know the way I can keep the Elasticsearch cache consistent/forever or preventing old rollover index is refreshed (cache also will be cleared)
