Is it possible to search for all fields that have a null value?
eg:
define_index do
indexes title
...
indexes [owner(:first_name), owner(:last_name)], :as
=> :owner_name
set_property :delta => true
end
I can search like "@owner_name John Doe" and get all items owned by
John Doe, but I also need to have a search that returns all unowned
items, eg "@owner_name nil" is this possible?
Thanks.
