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