Ruby-on-rails: Get working but Post isn't - ruby-on-rails

Question

In very short.
When I have a form set as POST, the controller picks up the request, processes it and even starts to render the correct view. But the browser stays on the form page
When I switch the form to GET, it works
(yes, I remembered to change the route from get to post and back)
Here is the log:
Started POST "/sooth/search" for 127.0.0.1 at 2022-07-02 13:43:40
-0700 Processing by SoothController#search as TURBO_STREAM Parameters: {"authenticity_token"=>"[FILTERED]",
"search"=>{"name"=>"search keywords"}, "commit"=>"Save Search"}
Rendering layout layouts/application.html.erb Rendering
sooth/search.html.erb within layouts/application
I am rendering the search html page
The line above is a log message in the search.html.erb page
Rendered sooth/search.html.erb within
layouts/application (Duration: 1.0ms | Allocations: 148) Rendered
layout layouts/application.html.erb (Duration: 6.6ms | Allocations:
2710) Completed 200 OK in 15ms (Views: 11.3ms | ActiveRecord: 0.0ms |
Allocations: 4040)
BUT the search page is not displayed. Browser stays on the search form page.
Any hints deeply appreciated.
(And as you have probably guessed, I am day 1 with rails)
EDIT:
class SoothController < ApplicationController
include SoothHelper
def index
puts "sooth index"
template = get_query_template('sooth_search')
puts(template)
end
def search
form_params = params[:search]
puts 'searching' + form_params[:name].to_s
render "sooth/search"
end
end
ROUTES
Rails.application.routes.draw do
Rails.application.routes.draw do
get "/nlp_data", to: "nlp_data#index"
get "/sooth", to: "sooth#index"
post "/sooth/search", to: "sooth#search"
end

Your problem is you are trying to render the same page instead of redirecting to to the sooth page ,and secondly you cannot acces params directly in a post request, instead you must acces it from a strong param method
class SoothController < ApplicationController
include SoothHelper
def index
puts "sooth index"
template = get_query_template('sooth_search')
puts(template)
end
def search
form_params = sooth_params[:search]
puts 'searching' + form_params[:name].to_s
redirect_to "/sooth"
end
private
def sooth_params
params.require(:sooth).permit(:search)
end
end
