The icon means that the group has activated group chat on a certain Messenger. For example, icon X means that Windows Live Messenger (MSN) users can immediately join this group for real-time group chat.
It’s recommended to join groups with the icon of the Messenger you’re using.
You can also join groups without the icon of the Messenger you’re using, and request the group admin to activate group chat on this Messenger.
Why can not find your group?
Groups search only covers 80% of all the groups.
According to admin setting, some groups can not be searched out.
According to the region and language you selected, as well as the local policies, groups containing some sensitive words will not be listed in the search results.
