ruby on rails - How to set a 0 result in meta_search before user pressing a search button -

i'm using meta_search on rails 3 app. default (before pressing search button) meta_search returns elements of searching model. , want set 0 result before user pressing search button or if search params blank.

i using meta_search follows:

def index  @search = article.search(params[:search])   if params[:search].blank?     @places = nil   else     @places = @search.all   end end 

what best way set 0 result if search params blank ?

thanks

i don't think that's meta search provides out of box can cheat it.

def index   @search = article.search(params[:search].presence || {:id_lt => 0})   @places = @search.all end
