Apple tests new search feature for the App Store that helps you find related apps3
But Apple is testing a new system. Let's say you are searching for News. Under the search bar, you will find a number of related search terms like "finance news," or "business news". With this method, the odds improve that you will truly find an app that will suit your needs.
But Apple might be able to do even better. Back in 2012, it acquired Chomp which creates a search engine for app stores. Chomp is said to have a recommendation and discovery service that would greatly improve App Store searches. Hopefully, Apple will decide to incorporate it into the App Store in the not too distant future.
