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)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("program implementing") OR ("program improvements"))) OR ("program implementinged"))~.
• 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"))*.
