[chef] Re: Why I cannot search by recipes attribute only. Other attributes in search are still working.

[Ranjib Dey < >]

Recipes and roles are two node attributes, populated during node building, as part of chef run (check client.rb for phases in a chef run). Iteresting values of these two attributes comes from run list expansions, which populates an array of recipe as it parses the items in run list. Note, both are  automatic attributes, some thing similar to ohai.

Now,

if you want to check all recipes against a node, if you can use the run_context.loaded_recipes (most probably). this trick will work as long as you are searching against the current running node and the recipe you are searching is included before the code block where you are checking this.

We internally use a handler  that exposes these info as node.chef_metrics.loaded_recipes (with few other staff).
