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.

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！

请问中文可以使用suggester吗？

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

阮老师，有个问题迫切得到回复，搜索 联想推荐+结果聚合数量，求问怎么解决怎么分词入库。

下面是官方文档给出的解释：popular 和 always 的区别是：popular 在检索到了查询的词条的前提下还寻找到了其他"相似的"词条，然后"只"返回那些在所有文档中词频比查询词条更高的词条；always 是只要相似就返回。 missing: Only provide suggestions for suggest text terms that are not in the index. This is the default. popular: Only suggest suggestions that occur in more docs than the original suggest text term. always: Suggest any matching suggestions based on terms in the suggest text.

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

阮老师，请问在使用completion suggester的时候，我如何根据结果排序，开发过程中比如我输入抑郁，出现三个文档，抑郁、依依、抑郁症，我如何让它们按抑郁、抑郁症、依依，这样展示
