How to use the Advanced Search function

Canto’s advanced search options give users the ability to dive even deeper into their searches to locate the desired asset.

  1. Move the mouse pointer over the magnifying glass icon in the search field.

    The extended search menu is displayed.

  2. Specify whether you want to search globally - i.e. in the entire library - or only within the currently displayed results, e.g. within an album.
    You can use the Within Results feature to narrow down your previous search term(s) - i.e. your first search is "tree" and you want to narrow it down to only PDF files, go ahead and hover over the magnifying glass, select Within Results and type in ".pdf".
  3. Multiple search terms can be combined in different ways. Separate search terms with space ( ), comma (,) or semicolon (;).
    • Select AND to find files whose metadata contains all terms from the search field.
      Entering "apple, orange" finds all files that have the strings apple and orange in their metadata.
      You can exclude terms from the search with a preceding minus sign.
      Entering "apple, -orange" finds all files that have apple but not orange in the metadata.
    • Choose OR to find files whose metadata contains at least one of the terms in the search box.
      You can use OR to search for multiple search terms at once. Typing, for example, "101, 102, 125, 375" will find all files that contain either one of these terms or a combination of several.
    • Use the wildcardsearch (*) if you do not know the exact search term.  The input of "*hans" and "hans*" finds all files, in whose metadata the character string "hans" occurs at any place, e.g. Hanswurst, Buchanstalt, Chanson, Schmalhans, ...  The terms can be combined with AND as well as with OR.
  4. If necessary, specify under - Only within fields - in which metadata fields you want to search (default: all metadata fields are searched).


For Custom Fields with open text, a user may search for assets that do not have the field filled out or left blank by using the following key term _null_
