acts_as_ferret not searching at all

I am trying get acts_as_ferret working in my rails applications. I have installed the ferret gem. Installed the acts_as_ferret plugin.

This is what my model looks like now.

class User < ActiveRecord::Base
  acts_as_ferret :fields => {
    :first_name => {},
    :last_name => {}
  }

I have even tried

class User < ActiveRecord::Base
  acts_as_ferret :fields => [:first_name, :last_name]

Now I opened script/console

Here is the code I wrote and the response I got

 User.first 
 # => <Jobseeker id: 1, first_name: "Chirantan", last_name: "Rajhans"\>
 User.find(:first, :conditions => ["first_name like ?", '%chi%'])
 # => <Jobseeker id: 1, first_name: "Chirantan", last_name: "Rajhans"\>
 User.find_with_ferret 'chi'
 # => []
 User.find_with_ferret '%chi%'
 # => []
 User.find_with_ferret 'Chirantan'
 # => []

I even tried rebuilding the index. Did not work. The ferret log shows that everything is going well.

Here is the snapshot of the log.

I was testing this in development mode in the console. Is there a step that I have missed or do I need some indexing process running (Like in ThinkingSphinx)? What am I doing wrong?

Try a query of

User.find_with_ferret 'first_name:Chirantan'

It sounds like you are not searching all fields. You need to use the default_field option if you want to specify fields.
