WhatsApp Business is testing an update that allows s to filter their searches and easily find messages that are sent by people in their s list and others. The advanced search filters would also help businesses look at all unread messages on the app in one go. In addition to the new business-focussed change, WhatsApp is found to be creating a group when you would create a community. This group may allow community s to share messages with their communities.
As per a iOS that brings three distinct search filters, namely s, Non-s, and Unread.

These filters will help WhatsApp Business s to quickly look at messages they have received from their s, unknown numbers, or unread messages in one go. s can also combine different conditions including searching for the chats where their s have sent a photo or video.
WABetaInfo has shared a screenshot to give a Idea about the update. The screenshot has been taken from WhatsApp Business for Android. The source, however, said that the same feature has also been rolled out for beta testers on WhatsApp Business for iOS.
Similar to enhanced search for WhatsApp Business s, WhatsApp was recently spotted testing the ability to let regular s filter out their nearby business searches with filters including restaurant, grocery store, apparel, and clothing.
Additionally, WABetaInfo has found that WhatsApp could create a group when s create a community. It is speculated to allow community s to send messages to all groups linked to their community. The particular group may also have read-only access for everyone except group s.

Last month, WhatsApp was seen working on a feature to link groups to a community. That change appeared for both iOS and Android s, though it has not yet been provided publicly. WhatsApp has, in fact, not yet confirmed when exactly we could see communities on its platform.
