Wild card tag search

It would be great if you could search with a wildcard in front of, or inside a string. This is good for those who use nested tags. For example, if you set up tags that follow a logical order, say, #Buy.Food or #Eat.Food and you wanted to search for all tags that had “Food” in them, it would be good to search for “#Food" to bring up all tags these tags (with "” being the wildcard, obviously). At present, the wildcard exists only after the search string meaning that a search for “#Buy” delivers the same results that have “#Buy” at the beginning of the string (this would be "#Buy* in my example).
