def partial_search(type, query='*:*', *args, &block)
  Chef::Log.warn("DEPRECATED: The 'partial_search' API is deprecated and will be removed in\nfuture releases. Please use 'search' with a :filter_result argument to get\npartial search data.\n")

  if !args.empty? && args.first.is_a?(Hash)
    # partial_search uses :keys instead of :filter_result for
    # result filtering.
    args_h = args.first.dup
    args_h[:filter_result] = args_h[:keys]
    args_h.delete(:keys)

#search(type, query = '*:*', *args, &block) ⇒ Object

New search input, designed to be backwards compatible with the old method signature ‘type’ and ‘query’ are the same as before, args now will accept either a Hash of search arguments with symbols as the keys (ie :sort, :start, :rows) and a :filter_result option.

:filter_result should be in the format of another Hash with the structure of: 

:returned_name1 => ["path", "to", "variable"],
:returned_name2 => ["shorter", "path"]

a real world example might be something like: 

:ip_address => ["ipaddress"],
:ruby_version => ["languages", "ruby", "version"]


this will bring back 2 variables 'ip_address' and 'ruby_version' with whatever value was found

an example of the returned json may be: “ruby_version”: “1.9.3”
