About this widget

You are currently reading the documentation for React InstantSearch V6. Read our migration guide to learn how to upgrade from V5 to V6. You can still find the V5 documentation for this page.

Index is the component that allows you to apply widgets to a dedicated index. It’s useful if you want to build an interface that targets multiple indices.

This pattern is also called “Federated Search”, more information can be found in the guides dedicated to it.

The position of index in the widgets tree impacts which search parameters are applied. Search parameters created by widgets are forwarded to their child index widgets.

<Index indexName="instant_search">

</Index>
indexId
type: string
default: value provided for indexName
Optional

An identifier for the index. Providing an indexId allows multiple Index to target the same index as if they were two different indices. If multiple Index share the same indexId, the state will be shared; meaning that anything applied to one Index like a refinement will also be applied to the other ones sharing the same id.
