Any idea why this is? Both searches have the Newest tab selected. But maybe I'm missing something equally obvious (wouldn't be the first time :))
EDIT: This is the multi-tag link: https://stackoverflow.com/questions/tagged/sql+or+sql-server+or+mysql+or+perl+or+regex+or+c
This is the single-tag link: https://stackoverflow.com/questions/tagged/sql
EDIT2: Retagged as bug hoping for some info on if this is by design or not.
