I often use this site's advanced search to find my next manga to read, and will often use the 'Only show completely scanlated manga' selection, which ends up being mostly one shots. I do not want to read one shots. They just leave me wanting for more. It would be great if I could separately exclude one shots while still looking for completed series. Thank you.

+1, came here to post the same thing

+1 I've run across wanting that feature too

Agreed. In hindsight, I wish one shots was a genre option (could be selected or avoided) could ease all the one shot related options. Something else that could help would be a search by a max/min on releases, so if someone wants to read a 30+ volume series they could find it or avoid it. 😛

Indeed, it is annoying. This is indeed a problem, when searching for complete series you also end up with one shots.
Can this function be added?

Even after dead, we raise from the ashes for the sake of manga.
