What are @mentions and #hashtags?

Use @mentions to notify others of your posts, and use #hashtags to make it easier to search and filter your posts.


An @mention is a method of notifying colleagues of your post. An @mention contains @username anywhere in the body of the post. Use the @mentions feature to mention specific colleagues and share your news with them. The mentioned users are notified of your post, even if they are not following you. You can use @mentions anywhere in HCL Connections.

@Mentions that specify your @username are collected and are displayed in the @Mentions filter on your Home page. You can only view @mentions that specify your @username.

Rules for @mentions

  • Symbols cannot be used in or following the @mention. For example, if you enter @John.123, your message is sent to the user @John, not @John.123.
  • The @ sign must be at the beginning of a post or it must have a space immediately preceding it.
  • @mentions do not work in a typeahead field.


A #hashtag is any word or phrase with the number (#) sign immediately preceding it. The # sign converts the word into a link. This makes it easy to find and follow a conversation about a topic. You can use #hashtags in status updates and in comments about status updates.

To search for content containing a #hashtag, simply click on the #hashtag directly from the status update. Or, go to the Advanced Search page, select Status Updates, enter the tag that you want to find, and select Search.

Rules for #hashtags

  • Use #hashtags only on posts that are relevant to the topic. It is suggested to use no more than three #hashtags per post.
  • Make sure that you separate #hashtag entries with a space.
  • The #hashtag must be preceded by a space. For example, if you enter 123#John or word#John, relevant posts are not displayed in search results for the #John hashtag.
  • A #hashtag must contain letters and numbers only, with at least one letter.
