LAMOST is on its commission period, and will plan to start survey in 2011. There will be more and more spectra data gathered by the Galaxy survey and the extra galaxy of LAMOST. Some data mining methods are developed to searching for rare data, such as Supernovae, CV stars, HVS, and metal poor stars. All the methods are examined by application in SDSS spectra. Some methods are presented in this paper, and applications are also shown. By these methods, large amount of rare objects will be found during the time when LAMOST survey performs.
