Perhaps you should try some spelling variations:
"program implementing" » "from implementing" (Expand Search), "trial implementing" (Expand Search), "program improvementsing" (Expand Search)
"program implement" » "program improvements" (Expand Search)
"program implementedingingedingededed" » "program improvementsedingingedingededed" (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 implement") OR ((("program implementedingingedingededed") OR ("program implementing"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"program implement\") OR (((\"program implementedingingedingededed\") OR (\"program implementing\"))))".
• Removing quotes may allow a broader search: (( program implement ) OR ((( program implementedingingedingededed ) OR ( program implementing )))).
• Adding a wildcard symbol may retrieve word variants: (("program implement") OR ((("program implementedingingedingededed") OR ("program implementing"))))*.
