Attributes improve performance if you're filtering by integers, floats
or timestamps. It's a different way of matching to string comparisons
for search queries.
As for strings, you can't filter by them yet if they're attributes.
You can sort, though (if it's a field flagged as sortable or an
attribute). If they're fields and you're using the :conditions option,
it's not actually filtering by them, it's just appending field-
specific searches to the query string.
Model.search 'blah', :conditions => {:foo => 'bar'}
is the same as
Model.search 'blah @foo bar', :match_mode => :extended
