ElasticSearch基本操作

es对文档的基本RestFul操作汇总

操作类型 请求方式 URL 格式 说明 示例
创建文档 PUT /{index}/_doc/{id} 指定 ID 创建文档，若 ID 已存在则覆盖 PUT /users/_doc/1携带 JSON 文档：{"name":"张三","age":30}
创建文档（自动生成 ID） POST /{index}/_doc 不指定 ID，ES 自动生成唯一 ID POST /users/_doc携带 JSON 文档：{"name":"李四","age":25}
查看文档 GET /{index}/_doc/{id} 通过 ID 查询单个文档 GET /users/_doc/1
更新文档（全量替换） PUT /{index}/_doc/{id} 同 “指定 ID 创建”，若文档存在则全量替换 PUT /users/_doc/1携带新 JSON 文档
更新文档（部分字段） POST /{index}/_doc/{id}/_update 仅更新指定字段 POST /users/_update/1携带：{"doc":{"age":31}}
删除文档 DELETE /{index}/_doc/{id} 通过 ID 删除文档 DELETE /users/_doc/1
批量操作 POST /_bulk 批量执行创建、更新、删除（需按特定格式） 格式示例：{"index":{"_index":"users","_id":"3"}}``{"name":"王五","age":28}

    缺失模块。
    1、请确保node版本大于6.2
    2、在博客根目录（注意不是yilia根目录）执行以下命令：
    npm i hexo-generator-json-content --save

    3、在根目录_config.yml里添加配置： 

      jsonContent:
    meta: false
    pages: false
    posts:
      title: true
      date: true
      path: true
      text: false
      raw: false
      content: false
      slug: false
      updated: false
      comments: false
      link: false
      permalink: false
      excerpt: false
      categories: false
