How are filtered indexes different from indexed views?
Filtered indexes can be non-unique, whereas indexed views must be unique. Filtered indexes are defined on one table and only support simple comparison operators. If you need a filter expression that references multiple tables or has complex logic, you should create a view.
What are the limitations of a filtered index?
