Many items unsearchable in the player shop

Can't find "Gunslinger Spin" , "Hurricane Hurl" , "Chaoslicer" , or the new Add S-ability capsules featured on the latest UQ page.

Long of the short of it, you need to see the items in-game first for them to show up in the partial search results (whether by doing a general search by category or by pulling up some list that has them), or you can type/copy&paste the full name of the item in the item name field, then go to one of the search options at the bottom without using the "search" button next to the item name field.
