Answer 1

Life would be easier if all your terms were sorted in ascending order.

I assume that your actual application is using a variable rather than a hard-coded string. So the solution should look something like this:

  select city, postcode, name
  from dealers
  where name = p_search_term OR
        postcode = p_search_term OR
        city = p_search_term
  ORDER BY case when postcode = p_search_term then p_search_term else 1 end desc
           , case when name = p_search_term then p_search_term else city end asc
