When you search in Bynder browser subapp using the name column filter, Magnolia shows you items that contain that name in both, the Bynder name and the Bynder original filename.

This causes confusion because the two fields are not the same and it's not possible to display the original filename field. 

In this situation, the name in Bynder is "32" and the original filename is "Madrid-8.3467008865514106077.jpg"

Searching "Madrid" with the filter column the image named "32" is shown. This happens because Bynder returns images that contain the word "Madrid" in their name or in their original filename

But then it is not possible to display the original filename value of the detail subapp. 

For our clients, this is confusing as they get a result and don't know why. 

Solution

I think the solution is add a new property called "originalFilename" to the class info.magnolia.external.dam.bynder.BynderAsset.

The information could be get in the "mediaItems->filename"
