Perhaps you should try some spelling variations:
"program implementing" » "from implementing" (Expand Search), "trial implementing" (Expand Search)
"program implementinged" » "from implementinged" (Expand Search), "trial implementinged" (Expand Search), "program implemented" (Expand Search), "program implementingrules" (Expand Search)
"program improvements" » "general improvements" (Expand Search), "term improvements" (Expand Search), "group improvements" (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 improvements\"))) OR (\"program implementinged\"))~".
• Removing quotes may allow a broader search: (((( program implementing ) OR ( program improvements ))) OR ( program implementinged ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program implementing") OR ("program improvements"))) OR ("program implementinged"))*.
