elasticsearch - 如何在Elasticsearch中找到与我的搜索字段相关的相关记录

Question

在Elasticsearch中，我想找到与我的搜索 Realm 相关的相关记录，例如stackoverflow相关的问题建议，这意味着匹配彼此相近的搜索结果。
例如，我从以下数据中搜索“男鞋”

“男鞋”

“女鞋”

“男鞋黑色”

“女鞋”

“女鞋粉红色”

“女鞋红色”

“男孩的鞋子”

“男鞋灰色”

“男鞋白色”

“男鞋绿色”

“男式鞋”

然后，如何通过搜索项目“男鞋”获得更多相关的元组？并且我如何也可以获取与同义词相关的数据。男士鞋类。
在Kibana中批量插入

POST /atomap/product/_bulk
{"index":{"_id":"1"}}
{"name": "Girl's Shoe"}
{"index":{"_id":"2"}}
{"name": "Men's Shoe"}
{"index":{"_id":"3"}}
{"name": "Women's Shoe"}
{"index":{"_id":"4"}}       
{"name": "Women's Shoe pink color"}
{"index":{"_id":"5"}}
{"name": "Women's Shoe red color"}
{"index":{"_id":"6"}}
{"name": "Boy's Shoe"}
{"index":{"_id":"7"}}
{"name": "Men's Shoe red color"}
{"index":{"_id":"8"}}
{"name": "Men's Shoe white color"}
{"index":{"_id":"9"}}
{"name": "Men's Shoe green color"}
{"index":{"_id":"10"}}
{"name": "Men's Shoe gray color"}
{"index":{"_id":"11"}}
{"name": "Men's footwear"}

我已经尝试过more like this查询:

GET /atomap/product/_search
{
  "query": {
    "more_like_this": {
        "like": "Men's shoe",
        "min_term_freq": 1,
        "min_doc_freq": 1
     }
   }
}

我的问题是。如何搜索相关单词？ 因为当我搜索“男鞋”时More Like This Query在顶部找不到“男鞋”。

创建同义词和字段映射:

PUT /atomap
{
  "settings": {
    "analysis": {
      "filter": {
        "my_synonym_filter": {
          "type": "synonym", 
          "synonyms": [ 
            "shoe,footwear",
            "color,colour"
          ]
        }
      },
      "analyzer": {
        "my_synonyms": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "my_synonym_filter" 
          ]
        }
      }
    }
  },
  "mappings":{

  "product" : {
     "properties" : {
        "name" : {
           "type" : "string",
           "analyzer" : "my_synonyms"
        }
     }
  }

  }
}

然后插入所有数据，然后运行以下查询:

POST /myshop/_search
{
    "query": {
        "query_string": {
            "default_field": "name",
            "query": "Men's shoe",
            "analyzer": "my_synonyms"
        }
    }
}
