searching for a specific metafield value not on the Criteria drop-down list

[Monte307]

Is there a way to find a particular metadata field value that isn't on the (presumably) fixed Criteria drop-down list?  For example, I would like to find files with the ‘Credit Line’ metadata field having a value of ‘Harvey’ (see attached screenshots).  I know the ‘All Metadata’ selection will work, but I just want to zero in on files with values for that particular meta field. 

In other words, is there a way to add, say, the ‘Credit Line’ metadata field to the Criteria drop-down list?

Not without scripting.

You may need to look into File > File Info > Raw Data to find the required info for the prefix and namespace fields.

You could also do this with EXIFTool.

Yes, something like:

exiftool -if '$credit =~ /Harvey/' -credit 'mac os/path/to the/folder to search in'

exiftool -if "$credit =~ /Harvey/" -credit "C:\win os\path\to the\folder to search in"

Thanks much for the example!  This worked for me (I'm on a Mac):  

exiftool -if '$credit =~ /Harvey/' -credit ~/Desktop

Thank you very much for your excellent guidance on implementing/running a script.  Much appreciated!  And it works fine specifying the photoshop Prefix.
