Profile? Quality?

Don’t know how to ask the question so I will present it as a problem. I just want to download the series Halo. Right now if I go to 1337x I see available downloads with names like: Halo.S01E06.1080p.WEB.H264-CAKES[TGx]
There are others but thats the type I want, 1080p.x264. In Sonarr I have Halo setup HD-1080p. Why does it not download this type?
How do I make a Profile? Quality? of 1080p.WEB.H264 so it will download that type of file?
