ElasticSearch实战（十七）-DSL增删改查

Posted 2021-10-06 张志翔ۤ

        本文我们来介绍一下增删改查语句怎么操作，后面会介绍批量增加/修改语句，特此记录便于日后查阅。

一、增加

POST company01/_doc/1
{
    "text" : "开放智能机器"
}

# 增加指定字段name的值为xiaoqiang
POST company/1/_update
{
    "script" : "ctx._source.name = \\"xiaoqiang\\""
}

二、删除

# 删除指定字段
POST company01/1/_update
{
    "script" : "ctx._source.remove(\\"name_of_new_field\\")"
}

# 删除一条数据
DELETE company01/1

# 根据多个条件批量删除
POST company01/_delete_by_query
{
    "query" : {
        "constant_score" : {
            "filter" : {
                "bool" : {
                    "must" : [
                        { "term" : { "mediaNameZh" : "5time悦读" } }, 
                        { "term" : { "codeName" : "美发" } }
