Perhaps you should try some spelling variations:
"design implementation and feeding program" » "an implementation and feeding program" (Expand search), "design implementation of feeding program" (Expand search)
"using computer code coding program" » "using computer code cloning program" (Expand search), "using computer code loading program" (Expand search), "using computer code cooling programs" (Expand search), "using computer codes coding program" (Expand search), "using computer model coding program" (Expand search), "using computer aided coding program" (Expand search), "using computer code codigo program" (Expand search), "using computer code according program" (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: "((\"design implementation and feeding program\") OR (\"using computer code coding program\"))~".
• Removing quotes may allow a broader search: (( design implementation and feeding program ) OR ( using computer code coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("design implementation and feeding program") OR ("using computer code coding program"))*.
