Problem Definition

There is no way to search via JQL to get accurate results in regards to issues / comments were a user has been @Mentioned For example, users have noted that you can sometimes get results for an advanced JQL query such as

comment ~ currentUser() 

However the ~ operator is unsupported for use with that function per Advanced searching - functions reference - Atlassian Documentation.

Also trying to search with a more basic set of terms like

comment ~ username

can sometimes return results, but in the current state of Jira Cloud it is not providing consistent  expected results (sometimes you see @ mentions here but not always), and given the recent changes to usernames in Atlassian Cloud, there does not appear to be a way to search via JQL for message content that includes @mentions

Suggested Solution

Creating a JQL function that can search for @ Mentions would be ideal
Or extending the comment field to be searchable by user accounts mentioned within it

Why this is important

It would be very helpful to be able to search, filter, and generally organize issues where you have been mentioned directly.

Workaround 1 (JQL)

Taken from comments, below.
Use the following JQL

summary ~ currentUser() OR description ~ currentUser() OR comment ~ currentUser() 

Workaround 2 (Slack integration)

Slack can notify you when someone mentions you in Jira.

• https://jira.atlassian.com/browse/API-80
• In any Slack channel send a message with /jira notify
• You will get a response with the following options:
