Updating Documents

Elasticsearch supports updating documents. index, type and id parameters are required to be passed. The fields needed to be updated in the document are passed inside the doc parameter which is inside the body.

local res, status = client:update{
  index = "my_index",
  type = "my_type",
  id = "my_id",
  body = {
    doc = {
      my_key = "new_value",
      my_new_key = "another_value"
    }
  }
}
