Every phrase we look up is shared across everyone using the site, and we refresh them on a rolling schedule through the day rather than all at once. A phrase nobody has ever asked about is one we have simply never had a reason to fetch.
Naming it in a report is that reason. It jumps the queue immediately, and in most cases the answer lands within a minute or two of your report finishing.
You do not have to do anything, and there is nothing you can run yourself. Reload the page and it fills in.
