Search with multiple tables

Hi, can anyone help me with the following action so that I can search
from not only one but two tables and fields. I would like to search from
name field in author table as well as name field in title table.

def search
@title_pages, @titles = paginate :titles, :per_page => 10,
:conditions => [“name LIKE ?”, params[:title][:name] + ‘%’ ]
@keyword = params[:title][:name]
render :action => ‘list’
end

Please help
