Search in 0.9.8


#1

Hi,

What changes I missed in search statement syntax?
I’m trying to use search to find all nodes which have hpc::client recipe in
chef 0.9.8:

clients = search(:node, "recipe:hpc::client)
but getting Internal Server Error. In 0.8.x versions it worked. In log file
on the chef server:
FATAL: Search Query to Solr
’/solr/select?rows=1000&sort=X_CHEF_id_CHEF_X+asc&start=0&indent=off&wt=ruby&fq=%2BX_CHEF_database_CHEF_X%3Achef+%2BX_CHEF_type_CHEF_X%3Anode&q=%2A’
failed

clients = search(:node, “recipe:hpc”) works just fine. I also tried
"run_list:recipe[hpc::client]", the same error. What is the right way to
use search?

As a temporary solution, I use following expression:
clients = search(:node, “:”).select { |e|
e.run_list.run_list_items.select{ |i| i.name == “hpc::client” }.any? }.map{
|e| e[“ipaddress”] }

Thanks,

The recipe is part of the run_list attribute, so you need to search in run_list[]. You also need to escape things ( ‘[’ in particular) to solr with “”. I find the easiest way of doing this is to use ruby’s alternate quoting syntax. For example:

nodes = search(:node, %Q{run_list:"role[#{app["server_roles"][0]}]" AND app_environment:#{node[:app_environment]}},

More simply (following what you are attempting to do):

clients = search(:node %q{run_list:"recipe[hpc::client]"}

(The difference between %q{} and %Q{} is the same as between ’ ’ and " ".)

Thanks a lot! This is much more elegant than what I used :slight_smile:
I think this example should be published on wiki to allow others know this
trick.
