Use hashtags in Live Feed
Hashtags are words marked with a hash symbol (#) in messages. Hashtags are a way to categorize messages by keyword or topic for improved search results.
For example, to identify messages associated with VPN questions, add the hashtag #VPN in the
message text.
Note:
Many of these features are part of Live Feed v2. If you are using
Live Feed v1, or have not activated Live Feed v2, see Legacy Live Feed.
