I want to show posts that are published prior to the current year. But I need to do it in a post feed, connected to search form. I have a tag setup for each year and assigned appropriately. So all previous years have that year tag. But i need to show all previous years in a single post feed. Because currently, i have another feed showing only the current year.

The previous year is acting as an archive.

I am using the POSTS post type.
