Perhaps you should try some spelling variations:
peptone complexity » tone complexity (Expand search), sentence complexity (Expand search), response complexity (Expand search)
rotations python » rotations method (Expand search), rotations without (Expand search), rotations on (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
