How to store and search for same values in a field

[kent120103 (Kent)]

Dear Elastic community,

My index contains following documents:

{.      
    "_index": "sametokensearch",
	"_type": "_doc",
	"_id": "1",
	"found": true,
	"_source": {
		"dob": ["202", "020", "20-", "0-0", "-03", "03-", "3-0", "-03"]
	}
}

{.      
    "_index": "sametokensearch",
	"_type": "_doc",
	"_id": "2",
	"found": true,
	"_source": {
		"dob": ["202", "020", "20-", "0-0", "-03", "03-", "3-0", "-04"]
	}
}

{.      
    "_index": "sametokensearch",
	"_type": "_doc",
	"_id": "3",
	"found": true,
	"_source": {
		"dob": ["202", "020", "20-", "0-0", "-03", "03-", "3-0", "-05"]
	}
}

There are three documents. Each document only has one field - "dob". This field is an array of "text" values. Its mapping is

{
    "sametokensearch": {
        "mappings": {
            "properties": {
                "dob": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                }
            }
        }
    }
}

Elasticsearch release = 7.5.0

Then I search for documents as /sametokensearch/doc/_search?size=50

{
    "query": {
        "query_string": {
        	"query": "dob: (202 AND 020 AND 20- AND 0-0 AND \\-03 AND 03- AND 3-0 AND \\-03)"
        }
    }
}

Result is all of the three documents.

But if I search for "dob: (202 AND 020 AND 20- AND 0-0 AND \\-03 AND 03- AND 3-0 AND \\-04)", result is the document of id = 2.

My first search query contains the same "text" value - "-03" twice. To me, it seems like the multiple occurs of "-03" token have been treated as single occur during search.

What I would like to achieve is

1. Searching for dob: (202 AND 020 AND 20- AND 0-0 AND \-03 AND 03- AND 3-0 AND \-03), returns only the document of id = 1. It is more like a precisely match.
2. Searching for dob: (202 AND 020 AND 20- AND 0-0 AND \-03 AND 03- AND 3-0), returns all the 3 documents. Because this field contains 8 values in all 3 document, but I only search for 7 of them.
3. The order of tokens is also considered. Since all of the 3 documents start with "202, 020". If I search for dob: (020 AND 202), there should be no match.

Is it possible to change my search query without changing my index?
