Elastic match documents containing all values in array - elasticsearch

Question

I have documents like the ones bellow in Elastic. Each document has some information and all mandatory permissions to access the document.
When I query, I would like to pass all user permissions and receive matched documents but am having difficulties with the query.
The documents:
{
"id": 1,
"permissions": ["a", "d"]
}
{
"id": 2,
"permissions": ["a"]
}
{
"id": 3,
"permissions": ["a", "b"]
}
{
"id": 4,
"permissions": ["a", "c"]
}
This is the closest I got:
{
"query": {
"bool": {
"should": [
{
"match_phrase": {
"tags.keyword": "a"
}
},
{
"match_phrase": {
"tags.keyword": "b"
}
},
],
"minimum_should_match": doc.tags.length
}
}
}
// Result are documents with id's 2 and 3.
I tried extending the "minimum_should_match" with the "script" but without success (apparently it does not support it):
"script" : {
"script" : {
"inline": "doc['permissions'].length",
"lang": "painless"
}
}
In an example above, with passed permission array ["a", "b", "c"], the output should be documents with id's 2, 3 and 4. ["a"] matches only document with id 2.
EDIT: Additional information
A document has up to 5 permissions, as well as the users, but the set of permissions is quite big (500+), so I am searching for a generic query. The data can also be transformed.
I am using Elastic 7.6
Any help is appreciated!

There is no efficient way to achieve your expected result, but apart from the below search query, you can even get your result using scripting, please refer this SO answer to know that.
You can use Terms Query that returns documents that contain one or more exact terms in a provided field.
Adding a working example with index data(taken the same as that given in question), index mapping, search query, and search result.
Index Mapping:
{
"mappings": {
"properties": {
"id": {
"type": "integer"
},
"permissions": {
"type": "text"
}
}
}
}
Search Query:
{
"query": {
"constant_score": {
"filter": {
"bool": {
"must": [
{
"terms": {
"permissions": [
"a",
"b",
"c"
]
}
}
],
"must_not": [
{
"terms": {
"permissions": [
"d"
]
}
}
]
}
}
}
}
}
Search Result:
"hits": [
{
"_index": "stof_64081578",
"_type": "_doc",
"_id": "2",
"_score": 1.0,
"_source": {
"id": 2,
"permissions": [
"a"
]
}
},
{
"_index": "stof_64081578",
"_type": "_doc",
"_id": "3",
"_score": 1.0,
"_source": {
"id": 3,
"permissions": [
"a",
"b"
]
}
},
{
"_index": "stof_64081578",
"_type": "_doc",
"_id": "4",
"_score": 1.0,
"_source": {
"id": 4,
"permissions": [
"a",
"c"
]
}
}
]
