Elasticsearch query to filter based on list

Question

Let us say we have following lists in ES. (Each list is part of separate document)

[1], [2], [1, 2], [1, 2, 3, 4]

If we query with the list [1, 2] , ES should return below results only.

[1], [2], [1, 2]

Note that using ' terms query ', will return [1, 2, 3, 4] also which is not the intended result.

Could someone suggest ES query for this scenario?

Answer 1

if the object is mapped as Nested datatype you can search something like listValue is 1, and also is 2, it will result on [1, 2] or [2, 1] because ES doesn't handle orders in simple arrays.

The nested type is a specialised version of the object datatype that allows arrays of objects to be indexed in a way that they can be queried independently of each other.
