example:

here is a document:

{
    "_source": {
        "name": [
            "beef soup",
            "chicken rice"
        ]
    }
}

it can be recalled by below query

{
    "match": {
        "name": {
            "query": "soup chicken noodle",
            "minimum_should_match": "67%"
        }
    }
}

but I only want it to be recalled by keyword hot beef soup or rice chicken hainan, is there any way except nested or span query to do this, thanks.

my es query is complex, anyone know how to rewrite it by span query

{
  "query": {
    "bool": {
      "filter": [
          ...
      ],
      "must": {
        "dis_max": {
          "queries": [
            {
              "match": {
                "array_field_3": {
                  "boost": 2,
                  "minimum_should_match": "67%",
                  "query": "keyword aa bb"
                }
              }
            },
            ......
            {
              "nested": {
                "path": "path_1",
                "query": {
                    "must": {
                      "match": {
                        "array_field_6": {
                          ......
                          "query": "keyword aa bb"
                        }
                      }
                    }
                  }
                }
              }
            }
          ],
          "tie_breaker": 0.15
        }
      }
    }
  }
}

You can use match_phrase but it will only work for entire phrase. if you want to do only keyword match on each element of array then it is not possible without nested or span as mentioned in document.

Arrays of objects do not work as you would expect: you cannot query each object independently of the other objects in the array. If you need to be able to do this then you should use the nested data type instead of the object data type.

When you get a document back from Elasticsearch, any arrays will be in the same order as when you indexed the document. The _source field that you get back contains exactly the same JSON document that you indexed.

However, arrays are indexed — made searchable — as multi-value fields, which are unordered. At search time you can’t refer to “the first element” or “the last element”.

Please try match_phrase query：

POST index1/_search
{
  "query": {
    "match_phrase": {
      "text": {
        "query": "chicken soup"
      }
    }
  }
}
