"relative" date range

Is there a way to search for messages using a “relative” date range, for example:
NOT defined as exact date, say “after 1/1/2018”
BUT defined relative to current date, say “in the last 6 months”

Sorry Matej, no luck with that one. Many have asked for the age criteria in searches, but it has not been added.

All I can think of is that if you want to use it in a Search Folder, you can use the date and update it weekly.
