Perhaps you should try some spelling variations:
"program implement" » "program improvements" (Expand Search)
"program implementinginged" » "program improvementsinginged" (Expand Search), "program implementingrules" (Expand Search)
"program improvementsedinging" » "program improvementachieving" (Expand Search), "program improvementshowing" (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 improvementsedinging\") OR (\"program implementinginged\"))))~".
• Removing quotes may allow a broader search: (( program implement ) OR ((( program improvementsedinging ) OR ( program implementinginged ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program implement") OR ((("program improvementsedinging") OR ("program implementinginged"))))*.
