[chef] Chef 12 duplicates nodes from a node search

[Stuart Cracraft < >]

Has anyone noticed in Chef 12 the following scenario? 

  nodes = search(:node, "hostname:*) 

returns duplicates of the last host added. 

So any cookbook which then uses the nodes variable gets a duplicate. 

That's in a ruby recipe and likewise with the cli: 

  knife search "hostname:*" -c /etc/chef/client.rb

also showing a duplicate of the last returned node.

If you knife node delete and knife client delete the duplicate, 

the next higher node is then listed as duplicated by the search() query.
