Perhaps you should try some spelling variations:
"program implementing" » "from implementing" (Expand Search)
"program implementinginginged" » "from implementinginginged" (Expand Search)
"program complementinged" » "program complementing" (Expand Search), "program complementslinked" (Expand Search), "program complementsingle" (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 implementing\") OR (((\"program implementinginginged\") OR (\"program complementinged\"))))~".
• Removing quotes may allow a broader search: (( program implementing ) OR ((( program implementinginginged ) OR ( program complementinged ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program implementing") OR ((("program implementinginginged") OR ("program complementinged"))))*.
