新建索引

curl -X PUT "192.168.3.162:9200/clusterlockexception_v02" -H 'Content-Type: application/json' -d'
{
  "settings": {
	"blocks": {
		"read_only_allow_delete": null
	},
    "analysis": {
      "analyzer": {
        "like_analyzer": {
          "tokenizer": "like_tokenizer"
        }
      },
      "tokenizer": {
        "like_tokenizer": {
          "type": "ngram",
          "min_gram": "1",
          "max_gram": "1"
        }
      }
    }
  },
  "mappings": {
    "_doc": {
      "properties": {

        },
        "url": {
          "index": false,
          "type": "text"
        }
      }
    }
  }
}'

新建索引时定义索引别名

在新建索引的同时，定义索引的别名，可以定义多个别名，不同别名

curl -X PUT "192.168.3.162:9200/my_index" -H 'Content-Type: application/json' -d'
{
  "settings": {
	// 省略...
  },
  "mappings": {
    // 省略...
  },
  "aliases" : {
        "alias_1" : {},
        "alias_2" : {
            "filter" : {
                "term" : {"key" : value }
            }
        }
    }
}'

删除索引

curl -X DELETE "192.168.3.162:9200/company_100406_v02_v02"

上面的命令需要指定特定索引名或者通配符表达式，索引别名不能用来作为删除索引的参数，通配符表达式被解析为相匹配的具体索引。

支持多索引语法，用逗号间隔。

删除所有索引，使用 _all 或者 * 作为索引参数。

禁止使用通配符或者 _all 来删除索引，在配置中设置 action.destructive_requires_name 为 true 即可。该配置可以通过使用集群更新配置接口来修改。

添加索引别名

curl -X POST "192.168.3.162:9200/_aliases" -H 'Content-Type: application/json' -d'
{
    "actions" : [
        { "add" : { "index" : "company_489521805720043520_v02", "alias" : "company_489521805720043520_alias" } }
    ]
}'

删除索引别名

curl -X POST "192.168.3.162:9200/_aliases" -H 'Content-Type: application/json' -d'
{
    "actions" : [
        { "remove" : { "index" : "company_489516259906600960_v02", "alias" : "company_489516259906600960_v02_alias" } }}
	]
}'

修改索引别名

该操作为原子操作

curl -X POST "192.168.3.162:9200/_aliases" -H 'Content-Type: application/json' -d'
{
    "actions" : [
        { "remove" : { "index" : "company_489516259906600960_v02", "alias" : "company_489516259906600960_v02_alias" } },
		{ "add" : { "index" : "company_489516259906600960_v02", "alias" : "company_489516259906600960_alias" } }
	]
}'

复制索引

curl -X POST "192.168.3.162:9200/_reindex" -H 'Content-Type: application/json' -d'
{
    "conflicts": "proceed", 
    "source": {
	    "index": "company_100406_alias"
    },
    "dest": {
	    "index": "company_100406_v02",
	    "op_type": "create",
	    "version_type": "external"
    }
}'

刷新缓存中的索引到磁盘

curl -X POST "localhost:9200/_flush?pretty"

返回

{
  "_shards" : {
    "total" : 270,
    "successful" : 135,
    "failed" : 0
  }
}

精确检索

实际需求：除了文件名模糊匹配之外，再添加按上传时间范围、上传人姓名、文件大小范围来检索文件信息

检索超时设置

全局超时设置，key为【search.default_search_timeout】，默认无设置

curl -X PUT "192.168.3.162:9200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d'
{
    "persistent" : {
        "search.default_search_timeout" : "30s"
    }
}
'
