Hi Yaxm,
I'm not sure about bitwise search operations, but you can index the
return value of methods, as well as ActiveRecord attributes.
You could write a method called "role_text" that returns a string
according to the value of role: "admin manager", and index that. Then
you can search: 'role_text:admin' and get all the admins.
Just make sure that the strings you use don't get tokenized ambiguously
(this depends on your analyzer I guess).
Hope this is useful.
John.
