:single_index isn't supported any more.

With current trunk the preferred way to declare an index is via the  
ActsAsFerret::define_index method, in a file called config/aaf.rb.  
There you may declare several classes using the same index like this:

ActsAsFerret.define_index('my_index',
                             :models => {
                               OneModel => {
                                 :fields => {
                                   :title => { :boost => 2 },
                                   :description => { }
                                 },
                                 :if => Proc.new { |r| r.published? }
                               },
                               AnotherModel => {
                                 :fields => {
                                   :title => { :boost => 2 },
                                   :another_field => {},
                                 },
                               :if => Proc.new { |r| r.should_index? }
                             }, :ferret => {
                               :default_field => %w( title description  
another_field )
                             })

No need to call acts_as_ferret inside your model anymore (though it  
will still work for the one index per class scenario).
my_index is the name of the index, to be used with ActsAsFerret::find:

ActsAsFerret::find("some query", 'my_index')

to only search records of a given class, find_with_ferret works as  
expected:

OneModel.find_with_ferret('some query')


Sorry for not documenting this stuff better...


cheers,
Jens
