The advanced search in File Storage Optimization includes criteria that can be customized. You can define the relationship between criteria and search values by using comparison operators. If you use multiple criteria, define the relationship between them by using AND and OR conditions. For criteria that allow multiple values, separate the values with a semi-colon (;) or a comma (,).
To add multiple criteria for search by using the AND condition, click the add
