Talvez debería tentar con algunhas variantes ortográficas:
"program complementing" » "program commencing" (Expandir procura), "program comprehension" (Expandir procura)
"program implemented" » "program improvements" (Expandir procura)
"term improvements" » "care improvements" (Expandir procura), "large improvements" (Expandir procura), "main improvements" (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: "((\"term improvements\") OR (((\"program implemented\") OR (\"program complementing\"))))~".
• Removing quotes may allow a broader search: (( term improvements ) OR ((( program implemented ) OR ( program complementing ))))~.
• Adding a wildcard symbol may retrieve word variants: (("term improvements") OR ((("program implemented") OR ("program complementing"))))*.
