Perhaps you should try some spelling variations:
peptone complexity » tone complexity (Expand search), sentence complexity (Expand search), response complexity (Expand search)
methods python » methods action (Expand search), pythons python (Expand search), methods method (Expand search)
based methods » based method (Expand search), mixed methods (Expand search), and methods (Expand search)
using based » using biased (Expand search), using base (Expand search), nursing based (Expand search)
coder » poder (Expand search), codes (Expand search), coded (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( coder peptone complexity control program ) OR ( using based methods python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder peptone complexity control program ) OR ( using based methods python programming ))*.
