No, sadly the search is still continuing, and as the plane has now been missing for over a month it's hard to see how there can be any hope of survivors now, though they still hope to find the wreckage and maybe eventually work out what happened.
The black box signal will probably not be working for much longer so will be of no use in locating the aircraft, though it's to be hoped that if/when the searchers find the plane the box itself will still be intact and its recording can be used for information.
The latest phase of the search is underwater. They are now using a recorder to try and locate the signals from the black box before they stop working. Two ships are searching within a radius of 150 miles - some debris has been spotted in the Indian Ocean which is thought to belong to the plane, but nobody can say for sure yet.
