Making entries expire after a certain amount of time
This functionality requires the Advanced Filter Extension, included in the Interstellar and Galactic packages.
Most of the time, if you are running a paid directory, you will want to make sure your entries "expire" after a certain amount of time (days, months of years), so you can charge your customers to renew their entry.
In the example above, we'll stop displaying entries if our date field is older than 30 days. If our entry date is the 1st of January, that entry will show up until the 30th of January. On the 31st, it'll disappear from our list of results.
