Hey,

how can i filter within a nested Property without change the result count?

Hit Example:

"_index": "1000",
"_type": "example",
"_id": "1337",
"_score": 1234,
"_source": {
    "id": 1337,
    "texts": [
        {
            "name": "FooBar",
            "lang": "de",
            "referrer":1
        },
        {
            "name": "FooBar",
            "lang": "de",
            "referrer":2
        },
        {
            "name": "FooBar",
            "lang": "en",
            "referrer":1
        },

But I just want certain text, filter by referrer and lang for every hit without to filter any other values of the hits.

I running on version 2.3 on AWS

Thanks helping me,

OK, got it. Then you might want to look at the nested type in the mapping.

Note that depending on your use-case, an alternative could be to denormalize your documents to look like:

{
    "parent_id": 1337,
    "name": "FooBar",
    "lang": "de",
    "referrer":1
}

And then run a cardinality aggregation to compute the number of unique parent_ids.
