Perhaps you should try some spelling variations:
"program implemented" » "program improvements" (Expand Search)
"program implementedededed" » "program improvementsededed" (Expand Search)
"program improvementsingeding" » "program improvementsincluding" (Expand Search), "program improvementsmitigating" (Expand Search), "program improvemntsincreasing" (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 implementedededed\") OR (\"program improvementsingeding\"))))~".
• Removing quotes may allow a broader search: (( program implemented ) OR ((( program implementedededed ) OR ( program improvementsingeding ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program implemented") OR ((("program implementedededed") OR ("program improvementsingeding"))))*.
