Perhaps you should try some spelling variations:
"program implemented" » "program improvements" (Expand Search)
"program implementededingeded" » "program improvementsedingeded" (Expand Search)
"program complementeding" » "program complementing" (Expand Search), "program complemented" (Expand Search), "program complementedmuch" (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 implemented\") OR (((\"program implementededingeded\") OR (\"program complementeding\"))))~".
• Removing quotes may allow a broader search: (( program implemented ) OR ((( program implementededingeded ) OR ( program complementeding ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program implemented") OR ((("program implementededingeded") OR ("program complementeding"))))*.
