I visit the Google Groups webpage. I enter a search term. Results are returned. There used to be a menu for me to select a date range. That seems to have gone.
i: is there a menu to enter a date range?
ii: are there search parameters that control the date range?
For my example I want anything before 2005/01/01 and nothing after.

The search helper/form only is displayed when the user is in a page for an specific group but not at http://groups.google.com
The search operator for posts before a date is
before:I.E. before:2005/01/01
For other search terms, go to Search Terms - Groups Help
