Elastic search 5, search from list by sublist - list

Question

I'm trying to search from an object that has a list property.
I need to be able to select all object that contains all sublist items.
ex :
If my object has [A,B,C] it should be returned for the given querys :
[A], [A,B], [A,B,C], [A,C], [C,A] ... (Input order doesn't have to match)
But if the sublist contains any element that is not part of the object list, it should not be returned.
ex :
[D], [A,D] ...
Those querys should not be valid.
I've managed to do it for the query with an existing sublist, but not when any item of the sublist doesn't exists.
Any ideas ?
Thanks !

Answer 1

Use comma seperate for sublist query item as a value for match query and set operator value to "and" as following:
Sample of document:
{
"Id": 1,
"Name": "One",
"tags": ["A","B","C"]
}
For sublist:[A,B]:
{
"query": {
"match": {
"tags": {
"query": "A,B",
"operator": "and"
}
}
}
}
I test in ElasticSearch 5.6.0 and 6.1.2

Assuming A, B, C, etc are mapped as keyword types, multiple bool query filter clauses would be one way
var response = client.Search<User>(s => s
.Query(q => +q
.Term(f => f.Badges, "A") && +q
.Term(f => f.Badges, "B") && +q
.Term(f => f.Badges, "C")
)
);
generates the following query
{
"query": {
"bool": {
"filter": [
{
"term": {
"badges": {
"value": "A"
}
}
},
{
"term": {
"badges": {
"value": "B"
}
}
},
{
"term": {
"badges": {
"value": "C"
}
}
}
]
}
}
}
A user document would need to have at least all of A, B and C badges to be considered a match.
A user document may well have other badges in addition to A, B and C; if you need to find documents that have exactly A, B and C, take a look at the terms_set query with a minimum_should_match* value set to the number of passed terms.
