如何在 ElasticSearch 中通过字典键进行搜索

Question

我是 elasticsearch 的新手，我需要编写如下所述的查询

我有一个像这样的文档的 elasticsearch 索引

数字表示书中单词的条目

{
  "words": {        # words listed below are different in every document
    "cat": 7,
    "monkey": 4,
    "mouse": 10,
    ...
}

我想按单词“cats”（不是“cat”）、“monkey”和例如“mous”来搜索文档。如何编写查询以在文档中找到“cat”、“monkey”和“mouse”并在计算分数时考虑它们的值？

更新。示例：我有文件

{                             # doc1
    "words": {        
        "cat": 7,
        "monkey": 4,
        "mouse": 10,
    }
}
{                             # doc2
    "words": {        
        "Cat": 20,
        "monkeys": 40,
        "mouse": 10,
    }
}
{                             # doc3
    "words": {        
        "Dog": 10,
        "monkey": 2,
        "human": 10,
    }
}
# I am searching by words "cats", "monkey", "mouse"
# I want to get doc2 as the most relevant result (because of words matches and entries quantity). 
# doc1 should be the second result (words do match, but there are less entries). 
# doc3 is the third result (too few words matches)

有什么想法吗？

Answer 1

我不知道我是否理解正确，但你想搜索“cats”和return包含“cat”、“monkey”和“mouse”的文档词。

运行我做的这个例子，看看它是否适合你。

PUT my-index-000001
{
      "mappings" : {
      "properties" : {
        "words" : {
          "properties" : {
            "count" : {
              "type" : "text"
            },
            "key" : {
              "type" : "text",  
              "analyzer": "english"
            }
          }
        }
      }
    }
}

POST  my-index-000001/_doc/1
{
  "words": [
    {
      "key": "cat",
      "count": "7"
    },
    {
      "key": "monkey",
      "count": "4"
    },
    {
      "key": "mouse",
      "count": "10"
    }
  ]
}

GET my-index-000001/_search
{
  "query": {
    "match": {
      "words.key":{
        "query": "cats"
      }
    }
  }
}
