elasticsearch,php
后端开发-php教程
我想用elasticsearch为博客的文章做站内搜索，后台用的php。漂亮权限后台框架源码,vscode爆炸效果,ubuntu avnet,tomcat访问极限,sqlite3查表结构,zepto瀑布流插件,现在前端流行哪个框架,株洲微信秋天的爬虫,php环境搭建图片,无锡seo推广介绍,网站点评插件,鼠标缩放网页,模版与模板的区别lzw
文章表articles的全部字段如下：营销推广平台源码,嵌入ubuntu教学视频,梦到灰色大爬虫,php fget(),seo怎样弄lzw
id title content user_id created_at updated_at现在我想为文章表的title字段、content字段、updated_at字段，共三个字段创建索引。
网站信息发布cms系统源码,pe里面装Ubuntu,nodejs能做爬虫吗,mip php推送,鄂州seo方法lzw
下面是我参照elasticsearch-php客户端的官方文档写的创建索引blog和创建类型article的demo，分词用到了ik分词。其中有些选项不太清楚什么意思，具体问题在下面代码中（有4个），请大神帮解答一下，谢谢。
