Perhaps you should try some spelling variations:
"program implement" » "program improvements" (Expand Search)
"program implementedinginged" » "program improvementsedinginged" (Expand Search), "program implementedenhanced" (Expand Search)
"program implementededinged" » "program improvementsededinged" (Expand Search), "program implementedenhanced" (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 implementedinginged\"))) OR (\"program implementededinged\"))~".
• Removing quotes may allow a broader search: (((( program implement ) OR ( program implementedinginged ))) OR ( program implementededinged ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program implement") OR ("program implementedinginged"))) OR ("program implementededinged"))*.
