Yes I just tried the 'dca' search and it does find images as part of the normal search but it doesn't bring images out of the DCA folder.
What happens is that keywords with dca in them are returned for example
broa
dcast
The image of yours that appears has the keyword
wonderlan
dcanada
You'll also notice that the images returned have a price as usual.
Hope this helps to put your mind at rest
