1. The pipeline is configured with an Amazon SNS subscription filter policy that sets a numeric matching condition.

   To verify that the event is indexed because it refers to an order whose value is higher than USD $100, on the **serverl-analyt-{{abcdefgh1ijk}}** page, choose **Indices**, **checkout\_events**.
