How to give different weights to exact, phonetic and fuzzy queries?

Elastic Stack Elasticsearch

Hi,
So currently I am using the following query:

{
    "_source": [
        "title",
        "bench",
        "id_",
        "court",
        "date"
    ],
    "size": 15,
    "from": 0,
    "query": {
        "bool": {
            "must": {
                "multi_match": {
                    "query": "knife",
                    "fields": [
                        "title",
                        "body"
                      
                    ],
                    "operator": "and"
                }
            },
            "should": {
                "multi_match": {
                    "query": "knife",
                    "fields": [
                        "title",
                        "body"
                    ],
                    "fuzziness" : 1,
                    "operator": "and"
                }
            }
        }
    },
    "highlight": {
        "pre_tags": [
            "<tag1>"
        ],
        "post_tags": [
            "</tag1>"
        ],
        "fields": {
            "content": {}
        },
        "fragment_size": 30
    }
}

What I want to achieve is that I want to give different weights to exact, phonetic and fuzy queries in the order exact > fuzzy > phonetic. How do I acheive this?

This is my mapping - (My analyzer is a Metaphone analyzer)

{
    "courts_2": {
        "mappings": {
            "properties": {
                "author": {
                    "type": "text",
                    "analyzer": "my_analyzer"
                },
                "bench": {
                    "type": "text",
                    "analyzer": "my_analyzer"
                },
                "citation": {
                    "type": "text"
                },
                "content": {
                    "type": "text",
                    "fields": {
                        "standard": {
                            "type": "text"
                        }
                    },
                    "analyzer": "my_analyzer"
                },
                "court": {
                    "type": "text"
                },
                "date": {
                    "type": "text"
                },
                "id_": {
                    "type": "text"
                },
                "title": {
                    "type": "text",
                    "fields": {
                        "standard": {
                            "type": "text"
                        }
                    },
                    "analyzer": "my_analyzer"
                },
                "verdict": {
                    "type": "text"
                }
            }
        }
    }
}

I shared a script here which can gives you some ideas.

It will use the analyzer you defined for the title field.
