We report on a search for extremely-high energy neutrinos with energies greater than 10{sup 6} GeV using the data taken with the IceCube detector at the South Pole. The data was collected between April 2008 and May 2009 with the half-completed IceCube array. The absence of signal candidate events in the sample of 333.5 days of live time significantly improves model-independent limits from previous searches and allows to place a limit on the diffuse flux of cosmic neutrinos with an E{sup -2} spectrum in the energy range 2.0x10{sup 6}-6.3x10{sup 9} GeV to a level of E{sup 2{phi}{<=}}3.6x10{sup -8} GeV cm{sup -2} sec{sup -1} sr{sup -1}.
