Answer 1

I think what you are looking for is

1. Update by Query

https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html

POST twitter/_update_by_query?conflicts=proceed
{
  "query": { 
    "term": {
      "user": "kimchy"
    }
  }
}

2. Delete by Query

https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html

POST twitter/_delete_by_query
{
  "query": { 
    "match": {
      "message": "some message"
    }
  }
}
