Elasticsearch多个术语可以促进 [英] Elasticsearch Multiple Terms to Boost

问题描述

在过去的一个小时里，我一直在尝试为多重增强查询找到正确的格式，有人可以帮助我正确地编写此格式吗?本质上，它是一个可以多次执行以下操作的查询.

i've been trying to find the right format for a mutliple boost query for the last hour, could someone assist me in writing this correctly? essentially it is a single query that can do the below many times.

这有效:

{
    "query": {
        "match" : {
            "title": {
                "query": "brain",
                "boost": 2
            }
        }
    }
}

这是我要实现的目标，但是没有用.在标题中搜索一个正常术语，在标题中优先搜索另外两个术语.

This is what i am trying to achieve but does not work. One normal term to search in title and two other boosted terms to also prioritise in title.

{
    "query": {
        "match" : {
           "title": {
                "query": "neuron",
            },
            "title": {
                "query": "brain",
                "boost": 2
            },
                "query": "birdsong",
                "boost": 3
            }
        }
    }
}

我想澄清的另一件事是:

Another thing i'd like to clarify is:

为了使ElasticSearch能够从 Web应用程序，它们必须作为Post HTTP请求提交?

In order for ElasticSearch to understand queries like the above from a web application they must be submitted as a Post HTTP request?

推荐答案

您需要像这样发出bool/should查询:

You need to issue a bool/should query like this:

POST index/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "title": {
              "query": "neuron"
            }
          }
        },
        {
          "match": {
            "title": {
              "query": "brain",
              "boost": 2
            }
          }
        },
        {
          "match": {
            "title": {
              "query": "birdsong",
              "boost": 3
            }
          }
        }
      ]
    }
  }
}

发送查询时，接受GET和POST.

Both GET and POST are accepted when sending a query.
