Perhaps you should try some spelling variations:
functions efficient » reactions efficient (Expand search), functional coefficient (Expand search), functionally efficient (Expand search)
efficient coding » efficient routing (Expand search), efficient cement (Expand search)
coder functions » power functions (Expand search), order functions (Expand search), colour functions (Expand search)
coding program » cloning program (Expand search), loading program (Expand search), cooling programs (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 functions efficient coding program ) OR ( api python python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder functions efficient coding program ) OR ( api python python python programming ))*.
