This chapter focused on getting your app indexed with the powerful CoreSpotlight framework. You saw how you can use user activities to index items that the user has already seen and how you can use searchable items to index content that the user might not have seen. You also learned how to make use of unique identifiers to ensure that you don't end up with duplicate entries in the search index. We also took a look at continuing user activities from either a user activity or a searchable item.

Once you found out everything about how CoreSpotlight can index your items, you learned about universal links and Web content. It's important to think about publishing content on the web because it helps your Spotlight indexing tremendously and it enables Apple to show your Spotlight results in Safari. We also covered the metadata that you should add to your web pages and Smart App Banners.

In the next chapter, we will focus on Universal Links and Smart App Banners and on adding metadata. We'll mainly do this to explore and implement Universal Links handling, but while we're at it, we should also make sure that the web portion we're implementing is as good as it can be so we can benefit from those sweet Spotlight advantages.
