The documents in my index have a field containing a list of all attribute terms, like
`"fieldA": ["attr1", "attr3", "attr7"]`
and for each attribute term, a field containing its weight, like
`"weight:attr1": 0.5, "weight:attr3": 0.3, "weight:attr7": 0.8]`.
I am using a `multi_match` query on the `"fieldA"` right now and I want to incorporate these weights into the score, so that the score of any query, document pair can be
`doc["weight:attr1"] * tf-idf(query, doc, "attr1") + doc["weight:attr2"] * tf-idf(query, doc, "attr2") + ...`.
I am wondering how I should construct this query.
I tried using `function_score` but since `function_score` is per query I have to explicitly list out all possible `"attr"`s at query time which is not ideal for me.
Thanks!

In Elasticsearch 7.x we will have [feature](https://www.elastic.co/guide/en/elasticsearch/reference/master/feature.html) and [feature vector](https://www.elastic.co/guide/en/elasticsearch/reference/master/feature-vector.html) data types, and together with [feature query](https://www.elastic.co/guide/en/elasticsearch/reference/master/query-dsl-feature-query.html) they will let you very efficiently process your request. You would be able to model your `fieldA` field as a `feature_vector` and run `feature_query` request on it.
