Why can't I find any products by partial match using the search bar in Products A/B Test?

Starting from January 23, 2020, our app uses Shopify API 2019-10 and GraphQL to ensure your partial search request will return the results.

Example: Your product title is "Cherokee Boys Grey Melange Track Pants".
So you can search by the complete title "Cherokee Boys Grey Melange Track Pants" to get a result, or by a partial text "Cherokee".
