Whenever I'm searching for a specific volume of manga or a magazine, including the issue or volume number doesn't really work. A lot of the time search will just pull up the first few issues, no matter what number I include. Or sometimes it pulls up a selection of issues based on what feels like a random criteria, but not the volume with the number I've inputted. A couple of examples attached.
All of the volumes I'm searching for have an entry and I can usually find them if I scroll down on the results page, but it's frustrating that they don't show up first.
