Rails encoded url query plus sign not properly decoded -

raw email

abc+2@gmail.com

for haml file, have javascripts this

$('#search_email').on('click', function(e){    var val = encodeuricomponent($('#search_email').val());    window.location.search = 'email='+val; });

in query url, shows correctly as

url?email=abc%2b2%40gmail.com

however, controller, when use debugger monitor, shows only

params[:email] = "abc 2@gmail.com"

does know happens, why rails decodes directly , in wrong way. thanks.
