# item is a hash, contacts in an array - using the Array#find or
Array#detect method (they're synonymous)
# assuming search_string contains the string you want to find
found_item = contacts.detect{|item| item.values.any?{|value|
value.include?(search_string)}}
or
found_item = contacts.detect{|item| item.values.join.include?
(search_string)}
then, it's simply a matter of getting the id value from the
found_item. As this is a hash, just found_item[:id] should suffice.
