　　官方关于elasticsearch 配置的说明
　　# These settings directly affect the performance of index and search operations
　　# in your cluster. Assuming you have enough machines to hold shards and
　　# replicas, the rule of thumb is:
　　#
　　# 1. Having more *shards* enhances the _indexing_ performance and allows to
　　#    _distribute_ a big index across machines.
　　# 2. Having more *replicas* enhances the _search_ performance and improves the
　　#    cluster _availability_.
　　#
　　# The "number_of_shards" is a one-time setting for an index.
　　#
　　# The "number_of_replicas" can be increased or decreased anytime,
　　# by using the Index Update Settings API.
　　#
　　# Elasticsearch takes care about load balancing, relocating, gathering the
　　# results from nodes, etc. Experiment with different settings to fine-tune
　　# your setup.
　　# Use the Index Status API () to inspect
　　# the index status.
