The current functionality of the "contains" operator allows for only one target in the condition. If you want to filter on multiple tags, you will need to add more events to your configuration. This can be done by using the "+ Add Another Event" link.
Here's how you can do it:
1. Use the "Filter" option in the Custom Query fields for a metric. 2. Add an individual filter for each tag you want to include in your analysis. 3. To add multiple values in one filter, use the "+ Add Another Event" link to add more events to your configuration.
Please note that the current documentation does not provide a method for adding multiple values in one filter in a more streamlined way. If you need further assistance, please reach out to the support team.
