Elasticsearch中任意顺序的模糊匹配词

Question

What I need to achieve is to match documents based on single field (product name, which consists of basically all possible filter values). I know it is not the most reliable solution, but I only have this one field to work with.

I need to be able to send a search query and the words in that query to be matched in any order to the name field (name should contain all words from the search query). Actually at this point simple match_phrase_prefix works pretty well, but what is missing there is fuzziness. Because another thing we need is to allow user make some typos and still get relevant results.

My question is, is there any way to have match_phrase_prefix-like query, but with fuzziness?

I tried some nested bool queries with match, but I don't get anything near match_phrase_prefix this way.

Examples of what I tried:

Pretty good results, but no fuzziness:

{
  "query": {
    "bool": {
      "must": [
        {
          "match_phrase_prefix": {
            "name.standard": {
              "query": "brand thing model",
              "slop": 10
            }
          }
        }
      ]
    }
  }
}

Fuzziness, but very limited matches:

    {
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "name.standard": {
                  "query": "thing",
                  "fuzziness": "AUTO",
                  "prefix_length": 3
                }
              }
            },
            {
              "match": {
                "name.standard": {
                  "query": "brand",
                  "fuzziness": "AUTO",
                  "prefix_length": 3
                }
              }
            }
          ]
        }
      }
    }

Using should above, I get more results, but they are way less relevant than the ones from first query.

Above can be achieved by simple match query

{
  "query": {
    "match": {
      "name.standard": {
        "query": "brand thing model",
        "operator": "and" ,//It means all of above 3 tokens must be present in any order
        "fuzziness": "AUTO" // value as per your choice
      }
    }
  }
}
