Steps

If a whole list is to be extracted, two replicas should be defined to calculate data extraction rules for extracting all items of the list repeatedly. On the other hand, one primary replica is enough to extract one single group of data snippets. In the following sections, we shall focus on how to create two replicas.

When a new bucket is created, the primary replica is created automatically. What should be done for this replica is to define mapping relations from data snippets on the target page to the properties.
