Thanks for Mark for the 'tuning'. Now that I think of this, can I add
another associated table (reviews) and include that into the search
also? What I mean is that if the models are

Person
        has_many :readings
        has_many :books, :through => :readings
                has_many :reviews

Reading
        belongs_to :person
        belongs_to :book

Book
        has_many :readings
        has_many :persons, :through => :readings

Review
                belongs_to :person


Now I would like to form a search like below

Person.find(:all,
                        :conditions => ["people.name LIKE ? AND
                                                        books.name LIKE ? AND
                                                        reviews.rating LIKE ?",
                                                        
"%#{params[:person_name]}%",
                                                        
"%#{params[:book_name]}%",
                                                        "%#{params[:rating]}%"])

How would I use :joins to make the above to work?
