Yeah, I think we've discussed creating a node object up front in the 
bootstrapper so that the node will at least exist and have its run list 
when chef-client tries to search (but even that would be subject to 
sleeping for a period and hoping solr had indexed it by the time the 
chef-client run needed to search).

You're probably better off doing it yourself and putting a node.save in 
your recipe and then retrying search until it shows up, or wrapping 
search with your own API that will combine the local node with the 
returned search results if the local node satisfies your search terms.
