Percolate already indexed documents in bulk

Elastic Stack Elasticsearch
3

Sure I'm exploring msearch as well.

Going back to the percolate search, are you saying that its possible to pass "documents" parameter in the context of already indexed document ?

Please note in my case both the search query and the actual document that contains the data are indexed within elastic as 2 separate indices.

As per - https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-percolate-query.html#_parameters_10

the following are the only parameters (with few more optional which I'm not mentioning here)
index - The index the document resides in. This is a required parameter.
type - The type of the document to fetch. This is a required parameter.
id - The id of the document to fetch. This is a required parameter.

Am I missing something ?
