创建索引

PUT /comma_analyzer_demo
{
  "mappings": {
    "properties": {
      "info":{
        "type": "text",
        "analyzer": "ik_smart"

#查询索引设置
GET /comma_analyzer_demo/_settings

删除索引

DELETE /comma_analyzer_demo

修改索引

1. 用新的索引配置创建索引
2. 重建索引，从旧索引导入数据到新索引
3. 删除原索引
4. 设置别名，无缝切换

# 用新的索引配置创建索引
PUT comma_analyzer_demo1
{
  "settings": {
      "analysis": {
        "analyzer": {
            "comma": {
            "type": "pattern",

  }
}
# 删除原索引
DELETE /comma_analyzer_demo
# 设置别名
PUT /comma_analyzer_demo1/_alias/comma_analyzer_demo

添加或更新数据

POST /comma_analyzer_demo1/_doc/1
{
  "info":"中间件工程师,虚拟化工程师,数据库工程师,存储工程师,网络工程师,系统测试工程师,运维工程师"
}

查询分词结果

GET _analyze
{
  "analyzer": "ik_smart",
  "text":"中间件工程师,虚拟化工程师,数据库工程师,存储工程师,网络工程师,系统测试工程师,运维工程师"
}

查询索引某条记录某个字段实际的分词结果

GET /${index}/${type}/${id}/_termvectors?fields=${fields_name}
# 例如：
GET /comma_analyzer_demo1/_doc/1/_termvectors?fields=info

查看别名都指向哪些索引

GET /*/_alias/comma_analyzer_demo
