this is what i am trying to accomplish

Post.find_by_contents(“artist:#{session[:srchstring]}*”)

a way to not repeat valuse of the same artist?

Not with Ferret alone. But if you combined Ferret with a custom active
record query this should be doable. Check out find_id_by_contents which
only gets the id values from ferret, and then use these to query your
unique artists.

find_id_by_contents is used internally by find_by_contents, too, so you
can have a look at the implementation to see how it is used.
