[chef] Search Index and roles

[Jose Luis Gordo Romero < >]

Hi!

I'm writing a cookbook that uses search to find nodes with a certain role in their run_list:

search(:node, "role:somorole") do |server|
   backend_servers << { "hostname" => server['hostname'],  "ip" => server['ipaddress'] }
end

But nothing is returned, then I test:

search(:node, "recipe:ubuntu") do |server|
  backend_servers << { "hostname" => server['hostname'],  "ip" => server['ipaddress'] }
end

But nothing is returned too, I'm sure that I have nodes with the role or recipes (from roles).

search(:node, "*") do |server|
  backend_servers << { "hostname" => server['hostname'],  "ip" => server['ipaddress'] }
end

Is working with all nodes, so:

Is that roles or recipes through 
roles in search in not supported?

Thanks in advance
Jose Luis
