When setting up routing with a multi-index search using the <Index> widget, you may encounter an issue where the routing does not update. This can happen when the <Index> widget does not have an indexId.
The solution is to add the indexId parameter to the <Index> widget. Providing an indexId allows different <Index> widgets to target the same Algolia index. It’s especially useful for the routing feature, and it lets you find the refinements that match an <Index> widget.
More information on this can be found in our multi-index search guide.
