Ruby on Rails

when the search gets submitted it only returns results for records that had the searched value in publicists

from my model:
 def self.search(search)
  where("headline LIKE ?", "%#{search}%")
  where("storyline LIKE ?", "%#{search}%")
  where("publicist LIKE ?", "%#{search}%")
 end

from my  controller:
def index
  if params[:search]
    @press_releases = PressRelease.search(params[:search]).order("dateline DESC")
  else
    @press_releases = PressRelease.order("dateline DESC")
  end
end
