It is given that @mrb prefers the inverse of c && s && n && !y. To calculate his musical preference regarding combinations of the set g = {c, s, n, y}, we apply DeMorgan's law to c && s && n && !y, producing: !c || !s || !n || y. This implies that @mrb will be happy given the presence of y in any combination, but if y is not present, neither can c, s, or n.

So, in the app, I do something like this:

  Item.all(:order => sort).select { |item| item.to_s.downcase.include? search.to_s.downcase }

Where sort is an array of fields to order by. By default (with lazy-loading enabled), the query output from DataMapper looks like the following (on a table of 8601 rows):

   ~ (0.142849) SELECT "id", "created_at", "updated_at" FROM "items" ORDER BY "artist", "title", "year", "label", "format"

x = 1
a = [2, 1, 4, 3]
[x] + (a - [x]) #=> [1, 2, 4, 3]
