baloosearch --help provides very limited documentation. I have a file where balooshow Example.jpg has line Description: EXIF Image Description So I thought I'd be able to do a baloosearch against that metadata field. But its completely unclear what baloosearch is searching against. The huge number of results suggests its doing a free search of the contents of every file, which is of little use. I expected syntax like baloosearch -t Description EXIF to returns a files with that metadata but its opaque what the -t field does Baloo 5.68.0 Mint 20
I think, for a single word, you can search with baloosearch Description:EXIF If you want to search for a phrase containing the words baloosearch Description:\"EXIF Image Description\" If you want to search for the exact phrase, I've found that baloosearch Description:EXIF_Image_Description works. There's more info under https://bugs.kde.org/show_bug.cgi?id=432004#c1
One more thing worth montioning, if you do a balooshow -x filename you will get a list of the metadata tags and values "read from" that file and you can use Baloosearch can search for these tags/values I'll close this now but feel free to reopen if you've more questions.
