类 Collapse

java.lang.Object

com.alicloud.openservices.tablestore.model.search.Collapse

public class Collapse
extends Object

Field collapse, which can achieve deduplication of results for a specific field.

Use case example:

In an app-based food ordering scenario, if I want to order the most popular dishes from the eight major Chinese cuisines. Using traditional methods, we might need to query the most popular dish for each of the 8 cuisine types separately. However, by setting Collapse to the cuisine type, we can return the 8 hottest dishes (one from each cuisine, as Collapse helps us eliminate duplicates). This fulfills the user's needs with just one query.
