Is it possible to perform a find\_by query using an 'or' statement? For example:

```
@product ||= Product.find_by_upc(params[:code]) if params[:code]
@product ||= Product.find_by_cspc(params[:code]) if params[:code]

```

As something like (does not work):

```
@product ||= Product.find_by_upc_or_cspc(params[:code]) if params[:code]

```

Thanks!
