I want to filter Jira tickets based on the reporter field containing a particular text, with this JQL:

project = "myproject" AND reporter ~ 'some_text' ORDER BY createdDate ASC

When I try this query, I get the following error:

The operator '~' is not supported by the 'reporter' field.

What should I do to make my query work? I tried using the "IN" clause as a workaround. I want the pattern to be generic and not restricted to a set of values.
