What is "Shop by" after I search on Alibaba.com App?

The "Shop by" function provides you with category-specific sub-groupings. For example, when you input the keyword of dress to search for Apparel products, groupings for multiple clothing styles are displayed above the results list for you to refine. Also, collections can appear in the search results and each collection contains many products pertaining to a specific topic, such as Most Popular on Alibaba.com.
