I have a server with 48GB memory and set ES\_HEAP\_SIZE to 32GB. 1. In this case I want to know, where to set indices.fielddata.cache.size and indices.fielddata.cache.expire and what is the proper value for the two configurations in my case. currently I set them in the elasticsearch.yml: indices.fielddata.cache.size: 16GB indices.fielddata.cache.expire: 1m 1. I also noted another two settings: indices.cache.filter.size and indices.cache.filter.expire, I want to know what's the difference between them and the default value of them. Thanks. -- 不学习，不知道 -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
