I’m not quite sure what it is you’re asking. Searches are and will remain limited to a specific subdomain since each subdomain is a separate database, and it isn’t possible to search across the entire archive at once. However, searches within a subdomain can be done across all subcategories in that subdomain.
If you wish to eliminate two tags while searching, you would type both tags in the search field, each preceded by a minus sign.
However, it is possible that the search function remains disabled at the present time, while our coder continues to make sure the site is properly secured against another crippling attack which would force us to place the archive into read-only mode again.
