Historically it is not unusual for an airliner to be lost at sea without a trace, even when the search was started within 24 hrs and the approximate location was known. Example, the Varig B707 PP-VLU, which went down in 1979 approximately 200 km from Tokyo.
Consequently, I read nothing into the failure to find a floating debris field.
I thought this case was the only one that nothing was found all the other cases had some debris found.
