How to search DPReview
I typed "photo ninja raw" into the search text box and the results list several posts on Photo Ninja ( including your questions ).
I think you are, perhaps, expecting more results that there are likely to be. It's not a widely used product, AFAIK, so I'd not expect many posts at all.
