/_cat/indices
/_cat/indices/{index}

/_cat/plugins
/_cat/fielddata

※ v，让输出内容表格显示表头;
※ pretty则让输出缩进更规范

• 集群状态

curl -X GET "localhost:9200/_cluster/health?pretty"

• 节点简要信息

curl -X GET "localhost:9200/_cat/nodes?pretty&v"

• 节点详细信息

curl -X GET "localhost:9200/_nodes/stats/http?pretty"

※ http这里可以添加的属性还有indices, fs, http, jvm, os, process, thread_pool, discovery等。

• 分片状态

curl -X GET "localhost:9200/_cat/shards?v&pretty"

索引管理

• 索引列表

#health 过滤条件，s 排序规则
curl -X GET "localhost:9200/_cat/indices?v&health=yellow&s=docs.count:desc"

• 新建索引

curl -X PUT "localhost:9200/my_index" -d 
'{
    "settings" : {
        "index" : {
            "number_of_shards" : 3, 
            "number_of_replicas" : 2 
        }
    }
}'

• 删除索引

curl -X DELETE "localhost:9200/my_index"

• 分词搜索

curl -X POST "localhost:9200/my_index/_search" -d 
'{
  "query": {
    "match": {
      "question": "地址"
    }
  }
}'

• 完全匹配搜索

curl -X POST "localhost:9200/my_index/_search" -d 
'{
  "query": {
    "match_phrase": {
      "question": "详细地址"
    }
  }
}'

• 别名

# 查看
curl -X GET "localhost:9200/_alias/my_index?pretty"

# 增加
curl -X PUT "localhost:9200/my_index/_alias/my_index_alias?pretty"

# 删除
curl -X POST 'http://localhost:9200/_aliases' -d 
'{
    "actions": [
        {"remove": {"index": "my_index", "alias": "my_index_alias"}}
    ]
}'

// TODO 以后用到再继续补充
