Elasticsearch根据字符串在数组中出现的次数进行排序 [英] Elasticsearch sort based on the number of occurrences a string appears in an array

问题描述

我有一个包含一个字符串列表的数组字段:即:["NY"，"CA"]

I have an array field containig a list of strings: ie.: ["NY", "CA"]

在搜索时，我有一个匹配数组中任何字符串的过滤器.

At search time I have a filter which matches any of the strings in the array.

我想根据搜索字符串出现次数最多的文档"NY"对结果进行排序

I would like to sort the results based on documents that have the most number of appearances of the searched string: "NY"

结果应包括:文件1:["CA"，"NY"，"NY"]文件2:["NY"，FL]文件3:["NY"，CA，" NY，" NY]

Results should include: document 1: ["CA", "NY", "NY"] document 2: ["NY", FL"] document 3: ["NY", CA", "NY", "NY"]

结果应这样排序

用户3，用户1，用户2

User 3, User 1, User 2

这可能吗?如果可以，怎么办?

Is this possible? If so, how?

推荐答案

对于那些好奇的人，我无法根据该单词在数组中出现的次数来进行增强.但是，我确实做到了以下几点:

For those curious, I was not able to boost based on how many occurrences of the word happen in the array. I did however accomplished what I needed with the following:

curl -X POST "http://localhost:9200/index/document/1" -d '{"id":1,"states_ties":["CA"],"state_abbreviation":"CA","worked_in_states":["CA"],"training_in_states":["CA"]}'
curl -X POST "http://localhost:9200/index/document/2" -d '{"id":2,"states_ties":["CA","NY"],"state_abbreviation":"FL","worked_in_states":["NY","CA"],"training_in_states":["NY","CA"]}'
curl -X POST "http://localhost:9200/index/document/3" -d '{"id":3,"states_ties":["CA","NY","FL"],"state_abbreviation":"NY","worked_in_states":["NY","CA"],"training_in_states":["NY","FL"]}'

curl -X GET 'http://localhost:9200/index/_search?per_page=10&pretty' -d '{
  "query": {
    "custom_filters_score": {
      "query": {
        "terms": {
          "states_ties": [
            "CA"
          ]
        }
      },
      "filters": [
        {
          "filter": {
            "term": {
              "state_abbreviation": "CA"
            }
          },
          "boost": 1.03
        },
        {
          "filter": {
            "terms": {
              "worked_in_states": [
                "CA"
              ]
            }
          },
          "boost": 1.02
        },
        {
          "filter": {
            "terms": {
              "training_in_states": [
                "CA"
              ]
            }
          },
          "boost": 1.01
        }
      ],
      "score_mode": "multiply"
    }
  },
  "sort": [
    {
      "_score": "desc"
    }
  ]
}'

results: id: score

1: 0.75584483
2: 0.73383
3: 0.7265643
