Perhaps you should try some spelling variations:
"program implement" » "program implemented" (Expand Search), "program implementing" (Expand Search)
"program implementedingedingeded" » "program implementededingedingeded" (Expand Search), "program implementingedingedingeded" (Expand Search)
"program complementing" » "program implementing" (Expand Search), "program complement" (Expand Search), "program completing" (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: "((\"program implement\") OR (((\"program implementedingedingeded\") OR (\"program complementing\"))))~".
• Removing quotes may allow a broader search: (( program implement ) OR ((( program implementedingedingeded ) OR ( program complementing ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program implement") OR ((("program implementedingedingeded") OR ("program complementing"))))*.
