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 (<http://localhost:9200/A/_status>) to inspect

# the index status.
