[chef] Re: Re: search returns for nodes sometimes reduced or empty

Hi Zac

Thanks for the response - no, I set a new, manually-set attribute 
(nothing from ohai) that contained an array of the nodes returned via 
searching on a combinatino of environment and role. Ie i search for all 
app servers in the staging environment, and get back an array of hashes 
containing the node information for 1-4 hosts. The problem is that if I 
have, say, 4 app servers that have that role assigned in that 
environment, sometimes search returns 4 and sometimes 3, sometimes 2.

I am hoping that the fix suggested by Ian works, since he says it 
worked for him. However, given that I don't really *need* search as such 
- I don't care what nodes are currently reporting as having the role, 
just what hosts are *assigned* that role in their definitions file - is 
there another better way that I can access this information from recipes 
other than via search?

Cheers

Dan
