           Summary: select images for display by combined tag query
           Product: digikam

          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist

         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: jjm keelhaul demon co uk

It's possible to display all images with a specified tag, by selecting the tag in the scrolling list.  But that is the limit: it's not possible to make more complex queries, e.g. "Holiday 2004 AND Venice" or "Venice OR Milan".

Photoshop Album on Windows has a limited facility for this: multiple tags can be selected for display (giving that OR option) and the selection can be inverted (a NOT option).  Selecting a tag also automatically selects all images in subcategories of that tag.

It would be a definite plus point if digikam could allow queries to be made using some sort of query expression - possibly a graphical tree view with AND, OR, NOT operators built up using a combination of popup menus and entry boxes.  For example:

  OR
   |
   +- tag "Milan"
   |
   +- AND
       |
       +- tag "Venice"
       |
       +- NOT
           |
           + tag "Canal"


Also allowing operators such as "Untagged", EXIF data, etc would be useful.
