#partial_search(index, query = nil, attributes = [], options = {}) ⇒ Array<ChefObject>, Hash

Perform a partial search the Chef Server. Partial objects or a smaller hash will be returned resulting in a faster response for larger response sets. Specify the attributes you want returned with the attributes parameter.

Examples:

ridley = Ridley.new(...)
ridley.partial_search(:node, "chef_environment:RESET", [ 'ipaddress', 'some.application.setting' ]) #=>
  [
    #<Ridley::NodeObject: chef_id:"reset.riotgames.com" normal:
      { "ipaddress" => "192.168.1.1", "some" => { "application" => { "setting" => "value" } } } ...>
  ]

Parameters:

  • index (#to_sym, #to_s)
  • query (#to_s) (defaults to: nil)
  • attributes (Array) (defaults to: []) —

    an array of strings in dotted hash notation representing the attributes to return

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :sort (String) —

    a sort string such as ‘name DESC’

  • :rows (Integer) —

    how many rows to return

  • :start (Integer) —

    the result number to start from
