A total of 192 objects (including 12 previously known CBes) were identified as CBe candidates with prominent HeI {lambda}4387, HeI {lambda}4471 and MgII {lambda}4481 absorption lines, as well as H{beta} {lambda}4861 and H{alpha} {lambda}6563 emission lines. These candidates significantly increase the currently known sample of CBes by about 8%. Most of the CBe candidates are distributed near the Galactic Anti-Center due to the observing strategy used for LAMOST. Only two CBes are in star clusters. These two CBes have ages of 15.8 and 398Myr, respectively. Description: We describe a search for CBes using LAMOST DR1. A total of 192 (with 12 previously known CBes) objects were identified as CBes with prominent HeI {lambda} 4387, HeI {lambda}4471 and MgII {lambda}4481 absorption lines, as well as H{beta}{lambda}4861 and H{alpha}{lambda}6563 emission lines.
