undefined method 'new_search' after upgrading SearchLogic

I got the same problem:

undefined method `new_search'

I am using this code

    @busqueda1 = Establecimiento.new_search(
      :conditions =>{
         :titulo_or_descripcion_like_any => params[:busqueda].split
      },
      :per_page => per_page,
      :page => params[:page]
    )
    @establecimientos = @busqueda.all

I installed will_paginate and pagination does not cause error, but
new_search method still doesn't work.

Has anyone figured out how to solve it?
