匹配的多术语查询错误结果

Question

看起来像我试图模糊匹配多术语查询时缺少明显的东西。

我想实现的是在提供“ Goleniow Heleniow”查询（带有Typo的City + District名称）时，仅获得“ Goleniow Helenow”。相反，我得到了所有文档。 基本上，我认为我尝试了所有组合

Minimum_should_match

，

操作器甚至fuzziness参数，没有令人满意的结果。 任何人都可以指出我想念什么？ 索引设置

curl -X PUT "localhost:9200/test-index?pretty" -H 'Content-Type: application/json' -d'
{
  "settings": {
    "number_of_shards": 1
  },
  "mappings": {
    "properties": { 
      "name": { 
        "type": "text",
        "index": true
      } 
    } 
  }   
}'

docs toIndex

curl -X POST "localhost:9200/test-index/_doc?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "Goleniow Helenow"
}'
curl -X POST "localhost:9200/test-index/_doc?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "Goleniow"
}'
curl -X POST "localhost:9200/test-index/_doc?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "Goleniow Jaworow"
}'

您可以使用

span_near

查询。
