InstantSearch iOS FAQ

For Flutter projects, you can utilize the Algolia Flutter Helper library, which is currently in beta. For more information, refer to the Getting Started Guide with Flutter.

For Dart projects, Algolia provides an official Dart API client. Alternatively, you can use the Algolia REST API directly.

Yes, we support React Native with our React InstantSearch library.

There’s a slight delay because events are sent in batches. This batching reduces the number of requests and network consumption on mobile. You can change the batch size if you need to. Larger batch sizes mean that there will be some extra processing on the server, so it could take a few extra minutes for events to be displayed. If you wish, you can also enable logging for more visibility of when events are sent.

Algolia supports all popular package managers: Carthage, CocoaPods and Swift Package Manager.

Each searcher gives you access to the query property via searcher.request.query. For example, if you want to modify the hitsPerPage parameter:

1
searcher.request.query.hitsPerPage = 30

When updating the filterState manually, you need to call filterState.notifyChange() for all components to update themselves with the new filterState. Algolia requires that you explicitly notify changes to avoid unnecessary requests when modifying several filters, and minimize the number of operations.

The filterState was designed to constantly connect with all other components for results to appear in real time. However, if you don’t need real time updates, you can make a copy of the original filterState, apply filters to it, and only copy back to the original filterState (the one linked to other components like the searcher) upon user action.

Subscribe to the searcher’s onError event to figure out what is going on. There could be a serialization issue, among other issues.

searcher.onError.subscribePast(with: self) { (_, queryAndError) in
  let error = queryAndError.1
  print(error)
}

You need to listen to the searcher result update, extract the userData which contains the banner information, and then use that information to update your UI.

searcher.onResults.subscribe(with: self) { (_, results) in
    let bannerDict = searchResults.userData?.first?.object() as? [String: String]
    let msg = bannerDict?["promo_content"]
    // display msg in a banner if it is available
}
