Summary: Option to search for empty/not empty or regular
expressions for text fields in advanced search
Product: digikam
Version: 0.9.2
Platform: SuSE RPMs
OS/Version: Linux
Status: UNCONFIRMED
Severity: wishlist
Priority: NOR
Component: Searches
AssignedTo: digikam-devel kde org
ReportedBy: brbpub gmail com
Version: 0.9.2 (using KDE KDE 3.5.5)
Installed from: SuSE RPMs
OS: Linux
The advanced search allows the logical operators "contains", "does not contain", "equals" and "does not equal" for textual items like image title, image caption, etc. This is a request to add a couple of logical operators: "is empty" and "is not empty". And it would be even better to allow for regular expressions, in which case the two proposed operators would simply be special cases that could be written "^$" and "^.+$" (using Perl's regex flavor, for the sake of discussion).
Here is a practical application. Recently, I wanted to create a search for all recent JPGs that had a rating of 2 or greater and for which I hadn't yet provided a comment. I can do the first three things, but not the fourth:
Rating | at least | **
As well as
Image name | contains | .jpg
As well as
Image date | After | 2007-10-08
I tried to select photos that had no caption with
Image Caption | contains | ''
and
Image Caption | contains | ""
and
Image Caption | contains | (that's a blank field)
but none worked.
Thanks for such a wonderful application as digiKam! I can't imagine how I would handle the billions of photographs I take without it.
