Talvez debería tentar con algunhas variantes ortográficas:
"program complementing" » "program commencing" (Expandir procura), "program comprehension" (Expandir procura)
"program implemented" » "program improvements" (Expandir procura)
"program implementinginged" » "program implementingrules" (Expandir procura)

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 implemented\") OR (\"program complementing\"))) OR (\"program implementinginged\"))~".
• Removing quotes may allow a broader search: (((( program implemented ) OR ( program complementing ))) OR ( program implementinginged ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program implemented") OR ("program complementing"))) OR ("program implementinginged"))*.
