  confidence和prefix_length具体是如何控制结果返回的？老师这些可以顺便讲一两句吧，就说一句可以通过修改配置控制返回结果，这不是废话吗？配置参数就是用来修改结果的啊

  popular和always在测试后没有区别啊，我在7.4版本上测试always，效果和popular是一模一样的，就算用算分最高的text进行匹配，option里也依然是空的。

  搜索推荐——有几种方式，大概原理是搜索的没有时，给出最小修改可搜索到的。

  老师您好，在本节中，有几个术语不是很明白，比如，sort:"frequency"，文档上说是文档频率，还有相似度评分，还有term自身，这几个排序相似度评分可以理解，但是term自身和文档频率不是很理解，希望老师看到能解答一下

  老师，有报错信息如下：
  {
    "error": {
      "root_cause": [
        {
          "type": "parsing_exception",
          "reason": "Unknown key for a START_OBJECT in [multi_match].",
          "line": 2,
          "col": 20
        }
      ],
      "type": "parsing_exception",
      "reason": "Unknown key for a START_OBJECT in [multi_match].",
      "line": 2,
      "col": 20
    },
    "status": 400
  }
  为什么ES在执行单字符多字段时，会产生multi_match原因呀

  老师，confidence看了文档也没看懂，感觉应该是推荐结果可信度的意思，文档我理解的大概意思是：为结果设置一个阈值，而这个阈值是由输入短语(text的值?)的分数和confidence计算而来，我改变这个值比如从1-100，结果确实变了，但又不知道怎么计算的，请老师解答下

  老师，为什么下面的不可以搜索出结果？
  GET /articles/_search
  {
    "suggest": {
      "term-suggestion": {
        "text": "rocks",
        "term": {
          "suggest_mode": "always",
          "field": "body"
        }
      }
    }
  }
  而下面的又可以搜索出结果？
  GET /articles/_search
  {
    "suggest": {
      "term-suggestion": {
        "text": "rock",
        "term": {
          "suggest_mode": "always",
          "field": "body"
        }
      }
    }
  }
  还有，confidence和prefix_length具体是如何控制结果返回的？

  官网看到这两段话 可能就是这个原因 穷用的是match_phrase_prefix
  
  Note that the postings highlighter is meant to perform simple query terms highlighting, regardless of their positions. That means that when used for instance in combination with a phrase query, it will highlight all the terms that the query is composed of, regardless of whether they are actually part of a query match, effectively ignoring their positions.
  
  
  The postings highlighter doesn’t support highlighting some complex queries, like a match query with type set to match_phrase_prefix. No highlighted snippets will be returned in that case.

  作者回复: 你是说东方网吧的问题吗？
  
  我看你用的是match query啊，你去看了有同义词么？

  感谢老师答复！环境是我自己的！ik我们老大装的！到时候我换官网下载的看看！

  作者回复: 你可以登录机器，查看一下ik插件的目录中是否安装配置了同义词词库。你这个现象感觉是配置了同义词词库导致的

  以上是我的索引 及mapping 提供一些数据给老师您看看
  我搜索‘’中国北‘’ 高亮部分会把 “京市”两个字做了高亮处理
  如果mapping 不设置分词器的话返回高亮部分是对的
  
  "highlight" : {
            "address" : [
              "</em>中国<em></em>北京市<em>朝阳区建国门"
            ]
          },

  请问大师，若是用户给的词已经是一个正确的term，如何在此基础之上再给出suggestion？
  比如库里同时有iPhone与iPhonePlus，用户输入了iPhone，是否能够给出iPhonePlus的suggestion？
