Hi,

I'm trying to find all the photos I took with my Canon EOS IX7. I use the search dialog as shown in the screenshot.
Background: The images I want to find are scans of my analog camera Canon EOS IX7. As the field EXIF:Maker was used by the negative scanner (Nikon COOLSCAN...), I have writen the camera name in the Exif field "UserComment".

I have tried it in different ways with different options, but the output is always "Finished: 0 file(s) found."
No idea what I am doing wrong. For example, when I search the pictures of my iPhone (with EXIF:Maker is Apple), all the matches are listed correctly.

I am thankful for any idea.

Regards
Thomas

I can reproduce...

For testing :
Select a jpg
Tools>Metadata>Transfer , "Add"
choose EXIF > User comment
write "Canon" in the blank field
Apply

... "Search" is unable to find Canon in exif comment field

and same problem on Exif XpComment field

Thank you for the quick feedback. So at least I know that I am not completely incompetent.
