如何将具有Multi_Match的筛选查询转换为通用条款的过滤查询 [英] How to convert filtered query with Multi_Match to filtered query with Common Terms

问题描述

我正在使用ES 2.0。我有以下过滤的查询与 multi_match ：

  {
filtered：{
query：{
multi_match：{
query：sleep，
fields：[title。 10，介绍*]，
cutoff_frequency：0.001，
运算符：或，
分析器：标准
} 
}，
过滤器：{
 ... 
} 
} 
  

由于停止词出现问题，我想用以下解释的常用条款替换Multi_Match： https://www.elastic.co/blog/stop-stopping-stop-words-a-look-at-common-terms -query

如何将以上 multi_match 替换为常用条款？我不知道如何处理基于常用条款的多个字段的搜索。

谢谢！

解决方案

在 multi_match 查询中指定 cutoff_frequency 时，您已经在使用条款，如您链接到的博客文章中所述：

常见条款也已被并入Match查询中，可以
通过将 cutoff_frequency 设置为0.001

对于匹配和 multi_match elasticsearch / reference / current / query-dsl-match-query.html＃query-dsl-match-query-cutoffrel =nofollow> cutoff_frequency 也提到这个事实。

I am using ES 2.0. I have the following filtered query with multi_match:

{
    "filtered" : {
        "query": { 
                "multi_match" : {
                    "query" : "sleep",
                    "fields" : ["title.*^10","introduction.*"],
                    "cutoff_frequency" : 0.001,
                    "operator" : "or",
                    "analyzer" : "standard"
                }
        },
        "filter" : {
            ...
        }
}

Because of stop words issue, I would like to replace the Multi_Match with Common Terms explained here: https://www.elastic.co/blog/stop-stopping-stop-words-a-look-at-common-terms-query

How can I just replace the above multi_match with Common Terms? I cannot figure out how to handle the search on multiple fields based on Common Terms.

Thanks!

解决方案

When specifying the cutoff_frequency in your multi_match query, you're already using common terms, as mentioned in the blog article you linked to:

"Common Terms has also been incorporated into the Match query and can be enabled by setting cutoff_frequency to a value like 0.001"

The documentation for match and multi_match on cutoff_frequency also mention this fact.
