Regular expressions in filters and automated rules
When you set up filters or automated rules, you use pattern matching to specify just the campaigns, ad groups, ads, or biddable items that you care about. If your patterns are relatively simple, such as "Show campaigns that contain ' - GB AdWords' in their names," you can use the basic pattern matching that DS provides. If your patterns are more complex, such as "Show campaigns with names that start with 'AdWords' and end with 'GB' or "US'", you can now use regular expressions.
