Hi Bluestar51,
Slightly off the current topic, is it possible that they have found some of the wreckage with their current search, but because of logistical restraints they are unable to explore those sights?
Quite on topic!
They might have found something without actually knowing it (further data analysis may later reveal some possible traces of wreckage) but I don't think that logistical restraints would have been an issue. Those vessels were fully equiped for recovering any wreckage, or simply to verify any doubtfull spot at will.
For those interested, there is also some good videos about the search means used during this last campaign posted on BEA's site (three parts):
