This would be cool. I’ve noticed the same humorous aspect that was exemplified with the term “counter” above; what I find especially humorous is, the way the weighting works, you can sort of narrow down the search by playing with the word: for “counter”, the nicest narrowing down that I quickly arrived at was with “ounterr”, with just a couple of “router” false positives. I already thought “counterrrrrrrr” gave me absolutely all “counter” instances, but “ounterr” gets me more, heh.
If you want a filter, search for an ilterr.
