Many Drupal users have reported that the Taxonomy:Vocabulary filter, which was an extremely useful setting in the Views module in Drupal 6, has been missing in the Views module in Drupal 7. Views itself is a widely used module and it is not clear why this setting was removed or whether it was intentional or not. However all is not lost and we can still achieve the same functionality in Drupal 7. Read onto find out more.
Here is the solution. If you add the relationship "Content: Taxonomy terms on node" in your View you can also choose which vocabulary you want to use. Then you can add a "Taxonomy term: Vocabulary" filter which will give about just the same functionality.
Hope that helps.
