It appears from news reports this week that the search for human remains is now concluded, but that some searching for aircraft pieces may continue. As noted in one article:
Crews have retrieved two wings, large portions of the fuselage, an engine, and other large pieces in a search that will soon enter its third week. The cockpit voice recorder is currently undergoing analysis at the National Transportation Safety Board headquarters in Washington D.C. The plane's ARES box, which records mechanical information, was also sent to the NTSB.
