The search bar in Edelweiss is where you can search for All, Frontlist, or Backlist titles:
You can make your search as broad or as narrow as you like. You can also filter your searches using Saved Filters. Instructions for doing so can be found here.
From within a title list (a catalog, a collection, list of review copies, an order, Buzz, etc.), you’ll see a Type here to find… box. This tool allows you to quickly jump to a specific title in that list. Start typing and you’ll see all the titles in that list that contain that specific combination of letters. Click to jump right to that title.
It’s worth reiterating here: the Type here to find… tool will only pull up titles that are in the list of titles you’re viewing.
