if you use knife search include condition "TO", "AND", "OR", "NOT" it will show bleow errors  
ERROR: Chef::Exceptions::InvalidSearchQuery: Invalid search object type nil (NilClass), must be a String or Symbol.Usage: search(:node, QUERY[, OPTIONAL\_ARGS]) `knife search environment QUERY (options)`  
`for example`  
knife search node "chef\_packages\_chef\_version:[\* TO 19]" -i  
knife search node "policy\_group:test AND policy\_name:policy\_name" -i
