How to pass large data set between controllers in Rails

Currently passing retrieved data using redirect_to which uses GET. Since in some cases data set is large, URI is too long and throws Bad Request error.

All online research says its a bad idea to pass data in GET body. Is there a better way to pass data to another controller?

Code Block 

def create
    response_body = http_get('/data/I/want')
    parsed_result = JSON.parse(response_body)
    check_response(parsed_result)
    redirect_to controller: :search_results, action: :index, results: parsed_result
end

end point called in create is search results so need to check if results are empty before redirecting and passing the data. I omitted this part from the code block

Any reason to put these code in create method? From my point of view, your code doesn't really create anything. It is just get some JSON data from a remote URL and redirect to search_results#index. Why not just load the JSON in search_results#index directly?

Update

It is too generous to use more than 3 routes for a search action. I have two suggestions:

  1. Search in remote JSON if you can control it. Just pass the searching keyword in URL and let remote resolve it.

  2. If you cannot control the remote JSON, do the search with AJAX call. In your search_results#index, makes an AJAX call to your something like search#new JSON route and fetch the filtered result.
