            Bug ID: 501615
           Summary: baloosearch doesn't find images with matching terms in
                    their Subject and Description exiv metadata
    Classification: Frameworks and Libraries
           Product: frameworks-baloo
           Version: 6.12.0
          Platform: Other

low-res sample JPG that has Subject and Description exiv metadata

SUMMARY

Pictures can have embedded Subject and Description tags. KFileMetadata extracts
these and `balooshow -x` shows them. But a simple Baloo search will not return
images with matching terms in subject and description.

STEPS TO REPRODUCE
(These assume you're on a Linux system like Fedora that appends "6" to all the
baloo command-line tools in KDE Frameworks version 6.)
1. Find a picture with embedded Subject: and Description: meta tags with
English words (I attached one).
2. Put it in a location that Baloo indexes, say
~/Pictures/pic_with_subject_description.jpg
3. Confirm that `balooshow6 -x ~/Pictures/pic_with_subject_description.jpg` has
"Cached properties" of the picture including the terms in the Subject and
Description, in the attached file these include "Miguel Rojas"
4. Search for the terms that aren't in the filename with baloosearch, for the
attached file `baloosearch6 Miguel Rojas`

OBSERVED RESULT

        Cached properties:
                Artist: Justin Sullivan
                Title: 62769411
                Subject: compost, environment, garbage, green, landfill,
recycle, reuse, trash, waste
                ...
                Description: SAN FRANCISCO, CA - DECEMBER 10: Recology worker
Miguel Rojas throws a bag of compostable material into his truck on December
10, 2010 in San Francisco, California. One year after the San Francisco board
of supervisors passed the nation's strictest recycling law, the residents of
San Francisco have composts more than any other city in the country, with a 200
percent one year jump in composting. The city has also achieved a better than
expected 77 percent diversion from landfill goal that was set at 75 percent by
2010, the nation's highest for any city. (Photo by Justin Sullivan/Getty

EXPECTED RESULT
I should be able to find this picture using terms from its subject and
description in Baloo search, but it doesn't work.
Looking at the `balooshow6 -x` output, it seems Baloo only puts the Artist and
Title attribute values (Justin Sullivan 62769411) into its Plain Text Terms.
Sure enough, I can find the picture searching for these. So Plain Text Terms
should include the terms from Subject and Description; I'm not sure about all
the many other fields.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:
KDE Plasma Version: 6.3.3
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.2

ADDITIONAL INFORMATION
Is there a way to search for terms in particular attribute values in Baloo?
E.g. `baloosearch --attribute description Miguel Rojas` specifically searching
the description?
