Elasticsearch script parameter containsAll with value from document - elasticsearch

Question

I'm trying to use an elasticsearch script query using the Java SDK to determine if a collection of IDs passed as a parameter contains all of the values in the indexed document.
Here is a simple example, that does not work, i'm expecting this to match the a document, but it doesn't.
The document attributes field is an array with a single item [2]
BoolQueryBuilder qb = boolQuery();
Map<String, Object> params = new HashMap<String, Object>();
params.put( "list", Arrays.asList( 1L, 2L, 3L ) );
String expr = "params.list.containsAll(doc['attributes'])";
Script script = new Script( ScriptType.INLINE, "painless", expr, Collections.emptyMap(), params );
qb.should( scriptQuery( script ) );
However, i've tried these various hard coded alternatives that do work
Hard coded .contains(2) works as expected
BoolQueryBuilder qb = boolQuery();
Map<String, Object> params = new HashMap<String, Object>();
params.put( "list", Arrays.asList( 2L ) );
String expr = "params.list.contains(2)";
Script script = new Script( ScriptType.INLINE, "painless", expr, Collections.emptyMap(), params );
qb.should( scriptQuery( script ) );
Hard coded .containsAll([2]) works as expected
BoolQueryBuilder qb = boolQuery();
Map<String, Object> params = new HashMap<String, Object>();
params.put( "list", Arrays.asList( 2L ) );
String expr = "params.list.containsAll([2])";
Script script = new Script( ScriptType.INLINE, "painless", expr, Collections.emptyMap(), params );
qb.should( scriptQuery( script ) );

Gotta cast the params.list elements before calling containsAll:
{
"query": {
"bool": {
"must": [
{
"script": {
"script": {
"inline": """
params.list.stream()
.map(num -> (long) num)
.collect(Collectors.toList())
.containsAll(
doc['attributes'].stream()
.collect(Collectors.toList()))""",
"params": {
"list": [
2
]
}
}
}
}
]
}
}
}
assuming your mapping truly defined the atributes as such:
{
"mappings": {
"properties": {
"attributes": {
"type": "long"
}
}
}
}
