tried already, default does not override value when param[:page] is undefined (nil) as I am passing merged params from controller in a brutal way   
```
  30     (params[:search] || {}).merge({                                                                                                                                                                       
  31       page: params[:page],                                                                                                                                                                                
  32       per_page: params[:per_page],                                                                                                                                                                        
  33     })
```

But I know how to rewrite that :)
