Is it possible with Drupal Views to have AND and OR in a filter set? I am attempting to build a view with four filters (A, B, C, D). With Views 3 it is possible to select whether you want these filters to be chained with AND statements or OR statements. Is there a way to configure views so as to chain some of them with AND and others with OR?

For example, ending up with a query that is similar to:

SELECT * 
FROM {table} 
WHERE A = 0
  AND B = 0
  AND (C = 1 OR D = 1)`
Looks like this is entirely possible with the Views 3.x branch. You can create custom Filter groups directly in the Views UI itself, and set the AND/OR for each group separately.
