词组之间的Elasticsearch OR操作 [英] Elasticsearch OR operation between phrases

问题描述

在Elasticsearch中是否有可能在单个查询中获取所有包含短语1"或短语2"的文档? 我知道要匹配一个短语，可以使用以下查询:

Is it possible in elasticsearch to get all documents that contain phrase1 OR phrase2 in a single query? I know to match a phrase, one can use the following query:

"query" : {
        "match_phrase" : {
            "title" : "rock climbing"
        }
    }

但是如果有多个词组并且目标是检索包含这些词组之一的文档，那该怎么办?

But how about a case when there are multiple phrases and the goal is to retrieve documents containing either of these phrases.

推荐答案

您可以将两个match_phrase查询包装在should子句中/en/elasticsearch/reference/current/query-dsl-bool-query.html#query-dsl-bool-query"rel =" nofollow>布尔查询:

You can wrap the two match_phrase queries in the should clause of a bool query :

{
  "query" : {
    "bool": {
      "should": [
        {
          "match_phrase" : {
            "title" : "phrase1"
          }
        },
        {
          "match_phrase": {
            "title": "phrase2"
          }
        }
      ],
      "minimum_number_should_match": 1
    } 
  }
}
